Go out, buy nothing but an iPad and tell me how good your computing experience is 12 months from now. No cheating. Not a single transaction on a single machine that isn't an iPad. I dare you.
It depends on what your "computing experience" requires you to do. Your average slashdot user needs a bit more than what an iPad can do of course, but my parents would be 100% fine with ONLY an iPad, since all they do is browse the web and check emails. Also, did someone say that the iPad was supposed to be used as a stand alone machine only? Your tone suggests that.
Can you link me to that other app store where I can buy applications for a non-jailbroken iphone?
Sure, can you link me to that document that FORCED you buy an iPhone, and not the phone that you wished to use?
