The Revo is fantastic. The standard 1Gb RAM config was a bit sluggish in Windows 7 MCE, but when I chucked an extra gig in there, it was fantastic. It's really quiet, fits to the back of the TV, and has all the connections I need.
I connected my 1.5Tb media drive via the eSATA port and all is good.
If you get one, just make sure it's one of the dual core Atoms with the ION chipset. For media, it's a dream
