Well as its what i do for a living, i can make an educated comment.
I-phone everyone loves them and to a point i can see why, but i just couldnt own one hate itunes hate texting on it.
N900 is the new maemo 5 os and it looks as though its gonna be good but as with all nokia flagships expect delays and bugs
Satio, one word crap apart from the camera.
Hero got rid of mine as you could not force landscape mode in all applications except browser and msg and the andriod os lacks polish
Blackberry storm tried one for 6 months reluctantly as i was doing a blackberry BIS/BES course so needed to get my head round it, thought i would hate it but it changed me. and i have just ordered a Storm 2 as im missing the blackberry experience, which will be with me tomorrow off to get it unlocked and then whack the o2 sim in
I honestly say the storm although not perfect is arguably the best phone i have ever had and i have had a lot of devices over the years
+ The iphone is just ludicrously priced
