Several years ago I got to go to Novell training. It was an interesting training, and I learned a lot. This week I am at SCCM training. The biggest things that I have learned so far: 1. Its kind of slow. There seems to be a lot of waiting going on. 2. It doesn't work nearly as often as I would like to see. They give you these pre-configured VM's. They should all work the same for everyone. Unfortunately they are buggy as hell.
This is really awesome, and you all have to check it out. http://www.raspberrypi.org/ Its a $25 computer, about the size of a usb key drive. Runs linux, has hdmi out. Did I mention its only $25?! Sweet!!!
