I have recently got a Compaq iPaq 3835 , despite that Compaq/HP had just released the new iPaq 3900 series ( new iPaq line that has a 400Mhtz Intel processor instead of the popular 206Mhtz StrongArm Processor). I really love the iPaq it came with a free 64Meg SD card. Prior to the iPaq I have used a handera 330 for the longest time( one of the fastest PalmOS PDAs prior to the Sony 66Mhtz ones ). With the PocketPc I can do a heck of alot more than just standard organization. If you deal with alot of microsoft oriented software, especially office ( you can get quickoffice for PalmOS however it does cost you money and isnt perfect but nice ), PocketPC would be the way to go.
Jornada wont be in production much longer, as the 560 is the last of the series, since HP/Compaq is continuing development using the iPaq line. the 3800 series is very nice and has a screen nearly identical to that of the 568, however if you get the 3835 , which is on sale with a 50$ maile in rebate, you also get a very nice screen cover and the expansion capabilities are far better than that of the Jornada.
Being a heavy gadget type person I Could strongly recomend the PocketPC platform , you can get some for about 300$ if pricing is a problem, but they dont have as nice the screen as the 568 or the iPaq 3800 series, or expandibility. It all really depends on what you will need. A good PocketPC can run you about 500 and above. If you goto CompUSA they have a deal where you can buy an iPaq 3835 and get a free 64Meg Secure Digital card, then you can submit a mail-in rebate for 50$ ( though when I submited online said my rebate ammount was 100$ )
If microsoft software was not an issue for you, I'd look into the Sharp Zaurus which is powered by Linux and uses the Qtopia desktop enviroment. Also Zaurus/Qtopia devices also have a fully working PalmOS emulator that can be downloaded provided you have a ROM image from an existing PalmOS device, such as myself I could get the rom off my Handera. Also the iPaq is capable of being replaced with linux if you are upto the extra work. Karl Blessing aka kb244{fastHACK}
