Mobile Computing: Top Pocket PC Programs

Pocket PCs ship with scaled-down versions of Microsoft Word, Excel, Outlook, Internet Explorer, and Windows Media Player that are already familiar to Windows users. And that's as it should be: The name "Pocket PC," after all, evokes a tiny Windows computer in your pocket.

Trouble is, aside from those Microsoft programs, there aren't a lot of useful, cool, interesting Pocket PC applications--at least not that I've seen. Quantity isn't really the issue here. There are about 10,000 programs available for Palm OS devices, compared to about 8000 for Pocket PCs, according to Handango, which sells software online for both platforms.

But quality is another matter. Based on my experiences, there simply aren't nearly as many worthwhile or intriguing third-party programs for Pocket PC as there are for the Palm OS. Nonetheless, I've found a few. The programs I recommend this week are inexpensive (up to $25), and most offer a free trial.

To read about my favorite third-party Palm applications, see last week's newsletter.

Pocket Streets
As far as Palm and Pocket PC mapping programs go, Microsoft Pocket Streets is by far the easiest to use. Pocket Streets puts interactive, color maps for U.S. and foreign metro areas within easy reach. You can download free maps for the U.S. and major European countries from Microsoft's Web site.

If you have Microsoft's Streets & Trips 2003 (or earlier versions), a mapping program that runs on Windows computers, you can create your own maps on your PC and copy them to your Pocket PC. Streets & Trips covers the U.S. and Canada only, however.

Arrow icons make map navigation a cinch, while a zoom tool lets you quickly move in or out for a better view. You can search for addresses or places, find points of interest, and add pushpins to map locations. When you tap on any point on a street, Pocket Streets gives you the corresponding address. Unlike Streets & Trips, you can't get directions--but that's what gas station attendants are for.

Pocket Streets costs $25 and can be downloaded from Handango. However, Streets & Trips 2003 includes Pocket Streets and goes for about $35, making it the better value. (Microsoft also offers a $10 rebate on Streets & Trips 2003 when purchased in retail stores.) Check out the latest prices using the PCWorld.com Product Finder.

Battery Pack 2003
A consistently popular download at Handango, Battery Pack 2003 from Omega One Software transforms the Pocket PC's Today screen from useless to useful by endowing it with interactive icons. At only $12, this software is a must-have for Pocket PC users.

Battery Pack 2003 is actually a bundle of utilities that includes a Battery Bar and a Program Bar.

The Battery Bar shows how much time the current battery charge has left (such as 3 hours, 36 minutes), the available amount of file storage space in main memory and on your storage card, and so on. Having this information right on the Today screen keeps you from having to dig for it through menus and helps you plan your PDA usage accordingly.

The Program Bar, another handy time-saver, places shortcut icons to frequently used programs and files on the Today screen. The bar can display up to five lines of shortcuts to scroll through.

Journal Bar
Another top-seller at Handango, Journal Bar is a cool little utility that feeds the latest headlines, stock quotes, weather forecasts, movie reviews and show times, TV listings, and sports scores directly to your Pocket PC's Today screen.

For all it delivers, Journal Bar takes up only a small piece of the screen. Using arrows, you scroll through the content line by line then click an item you want to explore. Selecting a headline, for instance, opens the related news article in Internet Explorer. The content is automatically updated when you synchronize your Pocket PC and have an active Internet connection. As far as I can tell, this doesn't noticeably slow down the synchronization process.

Journal Bar (from Omega One Software, maker of Battery Pack 2003) is an excellent way to have current news, weather, and other data on your Pocket PC--especially for those without wireless PDA connections. And it's only $12.

And a Few More
The following programs are available for Palm OS devices as well as Pocket PCs and have been reviewed in earlier newsletters.

Vindigo 2.0 ($25 annual subscription fee) is an indispensable guide to what's happening in dozens of cities, including info on restaurants, movies, bars, and so on. Read more about it in "Hands On: PDA Maps."

WorldMate 3.0 ($20) is a must-have for international travelers. It's a suite of utilities for figuring out what the heck time it is in Bangkok, getting updated weather conditions, easily converting currencies and measurements, and lots more.

Pocket Codes 2.0 ($8) is a cool little utility that lets you quickly look up U.S. and international area codes and time zones.

Notebook battery maintenance

Notebook from the birth of the day, the VGP-BPS5 battery on the controversy has never stopped, because the use of persistent notebook is a very important technical indicator, and battery capacity of the notebook's decision this important indicator. Because of technical reasons, the battery capacity will be affected by the use of the frequency-to-earth habits and the use of the storage environment and other factors to reduce or loss. In the end how can we maximize the use of the battery to play the effect of extending the battery life of it?

Many users of laptop batteries for use just to stay in the primary stage, how to protect the battery as well as the rational use of all batteries do not know. Whenever these big customers to complain about battery life is too short or long battery life is not at the same time is first of all carefully from the normal use of their own look for the reasons for this? Of course, these two problems caused by the vgp-bps5 battery does not rule out the reasons for their quality, but the vast majority of the current situation, improper use of man-made is a very common phenomenon.

Here are a few common errors in the future when the battery should pay attention to it! (Without all that for now the most commonly used lithium-ion battery)

For the first time the use of batteries, three times before the need to charge 12 hours?
This is totally unnecessary. Because the laptop has improved power management circuits and charging management system, when the battery reached saturation, the control circuit will automatically switch to the open state, so even if the charge is a long time to no avail.

In order to prevent the memory effect, should it run out of electric charge it?
Every time charge of vgp-bps5 battery discharge before it is not necessary, but also harmful, as they had proved the depth of discharge the battery life will reduce unnecessary, when the proposal to use about 10% of the battery can be recharged when the. When the battery, of course, there are still more than 30% of electricity when it would be better not to charge, because the memory effect is real.

Insert AC, the battery should be to win in order to prevent repeated charge and discharge it?
I suggest that is: do not have to. You might get lithium-ion battery discharge natural to refute me, saying that if the natural discharge after the battery if there is access to power will be reduced by repeatedly charging and discharging of the battery life. I give you a "no" answer to the following reasons:
1. Notebooks now have the power control circuit design of the features: When the battery is 90% (as most of the HP models) or 95% of the charge will be, and to achieve this through the natural discharge capacity of 2 hours a week , I would say when the batteries do not have to idle for about a month to complete in order to maintain the battery charge and discharge capacity at this time you should be concerned about the battery should be about training the body and not be left idle after the re-charge;
2. Even if the battery "unfortunate" was once again charge, the loss will not be brought about by the long period of time than the battery consumption caused by the large decline in the number.
3. Your data than you or your VGP-BPS5 notebook batteries are much more valuable, not only power all of a sudden you have a notebook injury, is unable to restore the data it is too late to regret the.

Long-term need to preserve battery power is full of it?
Read the following table on this clear: (percentage of saturation at the time of the initial value of the relative percentage)
Storage temperature of 40% of the state-of-charge 100% state of charge
0 degrees 98% (after one year) 94% (after one year)
25 degrees 96% (after one year) 80% (after one year)
40 degrees 85% (after one year) 65% (after one year)
60 degrees 75% (after one year) 60% (3 months)
It is clear that if the long-term preservation of the battery, as far as possible on the dry and low temperature environment so that the remaining battery power in about 40% of the ideal, of course, should be the best month to come up with a VGP-BPS5 battery that can ensure a good save battery , Also would not let the loss of full electricity and cell damage.

As far as possible in how to use the notebook to extend the use of time?
1. To reduce the brightness of the screen. However, large-screen LCD power consumption, reduce the brightness can be used to extend the time;
2. PowerPlay and open SpeedStep power-saving features, and so on. Now the notebook and display processor chips have a lower frequency and voltage to extend the use of the function of the time, open the corresponding options can significantly extend the battery life;
3. The use of hard disk drive and the deceleration of the software. If NERO DriveSpeed, PowerBooster software can reduce the drive, hard disk drives, such as speed, can effectively reduce the power consumption of vgp-bps5 notebook;
4. Make the best use of standby, sleep and other functions. When a longer period of time do not have a computer that allows notebook standby or hibernation, both to save power and extend the service life of the computer
