Man, I was hoping for a more accurate GPS. The 8330 seems to track me 50 feet at a time at best. However 4.5 seems to be a very nice upgrade so far.

The only bug I have noticed is with waking the device it selects whatever is highlighted. So I'm waking the device with the top button.

Its nice to be able to view word and PPT on the go. I also was able to view an excel file from an email no problem. Everything seems to be working great.
