had a treo 600, 650, 700p, then got sick of the buggy 700p and went with a MW xv6800 slider, couldn't stand having to slide open the keyboard all the time to do anything so went back to a centro.
Got the i770 friday.
couldn't be happer.
not a single thing i dont like.
it's snappy, has a great keyboard, the optical mouse is actually pretty cool. I could see it becoming the new standard instead of d-pads. Either wm 6.1 is way better then wm6 or samsung tweaked this thing very well. The UI us just much more user friendly and intuitive then the original WM6 on the XV6800. It's just as easy, user friendly, and one hand ready as palm os- but new and not 10 years old.
Comes with opera browser which takes some getting used to compared to blazer on palm OS or PIE on WM, but worth the learning curve. You can get like any page with it- and it's apple-like that it shows you the whole page and then you can zoom in to the part you want. It doesn't just zoom in graphically though- it refromats what you selected to fit the screen.
really very cool.
the only down side is it's so new that there's not a "go to" forum for it.
