It has a a 1.83GHz Core 2 Duo, TV Tuner card, 2GB of RAM, WiFi and a 300GB hard drive and all the other usuals you expect from Sony.
Its nice to see more cool PC designs becoming available.
Being Sony, you pay a lot more for it than you need to and it has no Blue ray (although you can fit 8.5GB on a dual layer DVD so thats not that bad)
I expect more manufacturers will start bringing out PCs like this soon and a lot cheaper.
