I think what's most obvious about computers and tablets in general is that they're used by a majority who casually tap into a tiny slice of a computers potential. The old "Facebook, Netflix, Word Doc, I'm Out" argument. It's very real. If someone even mentions "OS" or "Disk Space" when speaking about computers, they're already 10x more proficient at computers than the majority who buy them.
I have to agree here... I think most people here forget that there are tons and tons of people that use computers for mostly consumption type computing and for these people, this iPad is probably a great alternative because it really gives you a great experience and performance while being very portable.
Not everyone wants or needs full apps and honestly, I'm still not convinced that devices like the Surface Pro are the magic answer and I still side with Apple... if an application is not made for a touch screen, it's going to be a horrible experience on a device like a tablet. I can't imagine trying to use something like the desktop version of Excel on a tablet without going frigg'n nuts after about 5 mins.
