These things are so amazing!  There are several different models, This one being in the middle-low area.   All of these use solid state drives, and most of them come pre-installed with linux.  Most of us would of course wipe this and put a different flavor of linux.  These little guys start at around 299 for a 2gb model, and 399 for the 4g.  You can expand these with SD cards.  USB 2.0 ports, wireless... what more could you want.
