Did anyone know this? I just came across and I think it's a nice piece of retro gaming, although not only retro gaming.
It comes in some different setups. The PC inside includes a 160MB disk, MAME and about 100 preinstalled games. It has Wifi, and iTunes is also installed, so you can also use it as Jukebox. There's many more stuff, go have a look for yourselves at www.surface-tension.net, unfortunately I cannot access the site from here due to restrictions, will have a look when I'm home.
You can also find some videos on YouTube.
Only downside is the price, it's approximately 2500-3000£, which is quite expensive.
