In order to make sure I have access to my files and programs on the road I set up VNC on my office MacPro. This is all built in to the MacOS (and Win XP and 7 I believe) but not into the iPad. After much deliberation I purchased iTeleport for $24.99. Wow! Very cool. It takes a bit of getting used to because your finger is working like a mouse rather than as in the iOS, but once I got the hang of it I was happily checking out Ruth on Accordance. UPDATE: There is a preference for touch mode, so clearly I have a lot more playing to do!
Believe it or not, that is Accordance on an iPad!
(I was using it in landscape mode, hence the sideways screenshot.)
