Just bought a new CromeBook @ 129 bucks. Works for very simple task like only web browsing, email, and a few other limited task. Keep in mind that it's google-centric. However, the battery last for 3 days, it works great, way portable... and 129 bucks!
For recording, I have a MacMini on my cart that functions as a 3rd recorder, and basic functions like transfer files, wave agent stuff, and sound report. Plugged into one of my monitors though HDMI, and a wireless keyboard. This allows a lot while on your cart, even web surfin.
