I feel the same way Molekoi.
I picked up the 8525 the first day it came out, and have been playing with it since. Although it is WAY better than Symbian Nokia E61, and overall is a GREAT phone, I just have gotten too use to the simplicity and speed of my Treo 650.
I really like everything about the 8525, I was getting 900 kb for data in Vegas, and it came with great apps, not to mention Wifi, but I don't know why, I just cannot move on.
For people who are not STUCK on Palm OS, I think 8525 is a WONDERFUL phone, probably the best you can get. It's fast (not as fast as Palm OS), and it has great apps, and it is pretty user friendly (not as user friendly as Palm OS), and 900 kb is sweeeeeeeeet.
I soooooooooooooooooooooooooo hope Palm OS won't die, because it is seriously one GREAT OS.
Treo plus Palm OS = Great user experience and speed. It gets the job done, no BS.
