Yes, as we speak, I'm blogging from my treadmill. Here's what a projector, a piece of plywood, and a wireless keyboard/mouse will do for you!
I'm telling you, somebody who wanted to make a quillion dollars should set this up for people. I've now checked my email, surfed a couple of blogs, and written this little beauty, and hardly even known I've been walking for 28 minutes.
It's not perfect, but it's a fantastic time saver and hey, nobody had to go into therapy over what I looked like this morning. Especially me.
