PalmOne, the company formed from the merger of the old Palm company and Handspring, has announced new PDAs. The high end model is notable because the built in camera is a 1.2 megapixel, meaning it is actually useful as a camera, rather than as a novelty. In addition to all the usual organizer features, it has a voice recorder feature, can create Word and Excel-compatible files, and plays MP3 music files. It costs $299, and you'll need to invest at least $50 in a memory card to make it useful, so it's pretty pricey, but you do get a camera with it.
We're not really there yet, though, with respect to a truly useful device. Even with more memory, you can't store much music on it, and the 1.2 megapixel camera is where digital cameras were about 1995--low quality. Here is the dilemma: if you need a higher resolution camera, you still have to lug a camera around with you. If you want more than one or two albums to take on a trip (and you usually do), you need a much bigger MP3 player, like an iPod. And you still need a cellphone. So you have at least three devices strapped to your waist or stuck in your suit pocket or purse, along with all the usual charges, cables, and spare batteries. How do you avoid looking like a dork?
PalmOne's Treo, which includes the PDA functions, a camera, and the cellphone comes closest, but the first generation device has the usual growing pains. User reviews online are mixed at best, but the next generation of that device is likely to be much better.
