I paid a considerable amount less, but I got a deal through my work. (Sorry, can't get any more )
Even for $399, I would still consider it worth it. I'm sure Palm's are good products too, but using Windows Mobile for seamless sync'ing with my home and work computer is incredibly handy. It plays MP3's, has Bluetooth, does my laundry, etc.
Basically Bluetooth is a method for 2 or more devices to talk to each other wirelessly. (It's not 'Wi-Fi' though)
So, that could be PC's, PDA's, cell phone, etc.
I've only used it once so far. A co-worker who also has a Bluetooth enabled iPaq can wirelessly beam me files from across the room. Very handy.
Another co-worker has a Bluetooth enabled cell-phone, which allowed him to beam his contact/phone number list to his iPaq. Cool.
I plan on buying a bluetooth receiver for my PC, which is a small USB device that will allow me to wirelessly sync my Outlook information, as well as have web/email access on my iPaq while I'm in the room. Extra cool.
thanks Adam, I am sort of wondering whether it's not wiser to get a W-Fi ready one seeing as most places seem to be on track to get this technology now or fairly soon, even if half the places that have it don't work properly...
In retrospect, I would not recommend Toshiba line (I own the e310), and that appears to be the rest of the world's take. Also the Dell Axim is a poorly competitor. IPaq appear to be the way to go and they are usually the best pricepoint of the PDAs.
Look for some reviews online. Lots of info to go by.
