I thought better of you Nick! Have you fallen for the hype?! Hehe. Well I have to say, the interface would be the only reason for me actually getting one - it's still lacking in so many basic features that other "simpler" phones have covered that it has become too much of a fashion accessory for me, rarther than a piece of communcation technology. Ok so maybe my view of it is still based on the first iPhone incarnation without even basic functions like MMS, video recording and such like, which the "new" iphone 3GS covers (to be fair its a brilliant money making plan - release a version without basic features and then release a "better" version at a later date which includes the stuff that should have been there in the first place!).
As for the apps, can't say I know much about them, apart from the Carling beer drinking one where you tip your phone and the pint goes down etc. Lol. Useful!
