For those who travel for business the need for offline access to your desktop has always been a requirement but with internet coverage growing …..Broadband WiFi, cellular data cards, and now even on commercial flights with Delta and other airlines offering en route satellite based internet service things are changing.   Last week flying back to Atlanta I thought I would pony up the $9.95 and see how my vista xendesktop performed at 34,000 ft and 520kts. I was excited to find great usability and performance. Here is the recorded xendesktop session I  posted below.
