Jornada V mobile pro

I currently have a mobile pro 770 (easymate) but I think I would appreciate the bigger screen that an 880 or jornada 820 could give me-although the jornada has a USB how useful is it? and does it have a better CPU or refresh rate? are programs like pocket tv any good on the jornada?
if any one knows can they help?

I'm no expert, but I've heard something about the newer jornada's USB port. I heard it isn't really that useful unless you want to use just a USB mini-mouse... anyway I don't remember anything else but you should check up on some reviews.
g2g.

the specs are basically the same

MP770
CPU: MIPS 131 Mhz
RAM: 32 MiB
ROM: 24 MiB
OS: HPC Pro (CE2.11)

J820
CPU: StrongArm 190 Mhz
RAM: 16 MiB Upgradeable
ROM: 16 MiB
OS: HPC Pro (CE2.11)

MP880
CPU: MIPS 168 Mhz
RAM: 32 MiB
ROM: 24 MiB
OS: HPC Pro (CE2.11)(upgradeable to HPC2000-CE3, but you'll loose the USB port drivers in the process)

the only difference is the USB, which in both units will only allow you to plug mouse or other simple devices, so i suggest you stay with your current 770 or upgrade to a HPC2000 machine (like the MobilePro 790 or the Jornada 7xx series)

thanks-good advice
