I have both (also have a MacBook Air). They are completely different in the way I use them. the EEEPC sits in my car for if I need it whilst travelling around.

I have both (also have a MacBook Air). They are completely different in the way I use them. the EEEPC sits in my car for if I need it whilst travelling around. The iphone is for picking up stuff whilst I'm out, at dinner, at friends etc. The iphone is in my pocket and it my calendar, address book and all the other things I need instant access to. Whilst the EEPC is great in terms of form factor, its a computer and not what the iPhone is
