The other "solution" I found is Splashtop Remote, an app for iPad. It allows you to "drive" your main computer or laptop. So you could have the courses running on the computer but control them through the iPad from your couch. Sorry, not really a "study on the go" solution as it has to be on your local (home) network for Macs. They are working on it to be accessible anywhere on wifi for PC. That may be ready by now.
The app is in the App Store, or you could check it out on their web site.
