What the iPad means for startups

Any way to hook it up to a projector and use it to control a presentation there?<p>Speaking of which, I think I remember an app for iPhone or Android that would let you do presentations like that in a slightly roundabout way. You would upload your presentation to a webapp and then to give it, point a browser to some URL. Then you could use your phone to control the slideshow.<p>Anyone else remember what I'm talking about? I'm fairly certain I saw this and am not making it up.

A little too breathless for my tastes.<p>Imagine being able to carry all your documents around with you, being able to give a presentation anywhere...<p>Wait -- don't I already have one of these cool things? Isn't it called a notebook computer? 20 times the memory, bigger/smaller screen, open platform, etc.
