my 2 cents. Consider the Omnia
I just got the Omnia couple days ago and been glued to it. first thing i love is the size, well compared to I phone its very handy and feels good. The camera is friggin awsome, touch response is nice and optical mouse or 4 way nav is the best i have seen so far.
well win mo could be slow and annoying but best thing about win mo is that is easy to customize which i plan to do later. Another thing i love is hwo easy it is to sync, i havent even downloaded the companinon CD but its all reay to go without it. The "phone" quality is very good better than any other smart phone (except htc i never used them).
Opera webbrowser is great and device is very responsive to zoom function supports number of media players. I also love the touch or tactile feed back, little vibration when you touch the screen. Ok i could go on for ever.. oh one more thing you can record the friggin radio right to your playlist, oh did i mention it has FM radio player too.
humm some cons : The i 900 comes with fancy headphones and micro card this one does not (why eurpoeans have it better always)
The rsolution could be better but i gess its faster because its lower so its ok... (why euro....)but i mean the omnia hd, have you seen that thing, I have in person and played around with it... its awsome.
Typing kind of sux but omnia 2 that is coming out soon with have slide out keyboard so if its deal breaker, I will wait for that.
Win mo kinda sux, GPS locked by verizon, no apps or they cost too much, no 3.5 mm but have adapter.
Battery life could be better. Sorry for long post but hope it helps!
