Query: Energy Crisis

The iPAQ is a great machine if you only need to use it a few minutes here and there. Anything more requires frequent recharging. There's no going on business trips without the charger. Frankly, for the price I expected better. The screen is pretty, but I can't say I'm thrilled with the tradeoff... I'd rather use a monochrome device that still has juice when it's needed. It's embarrassing to whip out this hi-tech gadget only to have to borrow a scrap of paper to write down a phone number.I'm sticking with it for now, but I'm definitely on the look out for something that suits my needs better. Toshiba has just announced a Pocket PC that might be worthwhile if the battery life beats the iPAQ, Palm is planning on moving to more powerful ARM processors, and Compaq itself will have to keep on the move to compete.For now, if you're looking for a handheld that'll fit in your pocket and run all week on a charge, you'll need to look elsewhere.
