Forever Upgradeable PC
This little metal box is one of the tiniest computers available. It comes with dual display support with 1080p DVI, VGA, HDMI plus 6 USB and 2 SATA ports, all powered by two AMD Athlon 64 processors and some 2GB of RAM. The makers say that by changing two I/O boards you can virtually upgrade this tiny PC forever. You are not supposed to actually believe them but the idea of having your own light tiny PC in your pocket is really nice!
The Xi3‘s dimensions are 101mm x 92mm x 92mm. Small, indeed!
