^ Actually, smartphones and tablets would be pretty neat if they weren't... well, smartphones and tablets.
I'm using a MacBook Air right now, as it is the only computer I own; I also have an iPad my dad gave me for Christmas last year and a 5 year old iPod touch. That's three devices I have where there should only be one.
If I could merge the MacBook and the iPad, it would be absolutely perfect; say, a touchscreen for when you need a tablet, and also have a wireless keyboard in the case for when you need a laptop.
Just seems to me tablets would be a lot more useful if developers gave you the option of using them as regular computers if that's what you really need, or switching seamlessly into "mobile mode" or something.
