Should i buy an iphone ?

So ok i know what your thinking , isn’t he the one who said apple is crap that he would never get an iphone . That he wanted a HTC Touch HD , what changed ??

Well i want to get away from Microsoft in every form , and since everything is iphone ready i have been looking into them . I would buy the iphone 30something gig 3g{s} cause i need the extra space , but am i missing something is there another phone out there better than the iphone . Or are apple going to release a bigger capacity iphone in the not so distant future ? ?
I even plan on getting a mac and or changing the OS on my windows desktop to linux , thats how serious i am about getting away from M$.
If i do buy the iphone what apps free or pay for would you recommend.
