With a Kindle, iPhone, and Macbook air, I'm pretty well set for on-the-go computing … for now. But this demo of how Wired magazine is designing their magazine for a tablet (note: not the iPad) is a pretty clear example of the appeal.

The question I have: how long until the iPad could consolidate 2 of my machines? Already the iPhone replaced my iPod and my cell phone. 2 consolidated down to 1.

And already it's clear the iPad could replace the Kindle, although I appreciate the book-like feel of the Kindle. But could it replace the Macbook Air someday and be my one and only laptop? Hard to say, but that's going to take at least a year and probably two (right about the time I'll be looking for a change perhaps). But it'd be pretty cool if it could.
