I still find my 800w working well after a year and a half. I had to do a hard reset once and reload my programs, but it then worked fine. I'm waiting for the htc hd2 (with the huge screen) to upgrade.
sincing to windows
I have windows xp and absolutely no problems merely connecting the device to the usb port and follow instructions. there's an explore tab that lets you access both the device and the card.
