PocketMatrix

low down, no doubt.

The raw clock speed and power of the XScale makes it able to do things a 486 never could; video, MP3, OGG, whatever.

In games, though, let's just say current XScale devices sux0r... badly.

Argh, why can't someone make a PPC-sized 486/Pentium comp with a 640x480 screen and solid state instead of an HD? It would be almost perfect for classics... Keen, Doom, Quake, OMF.

Oops, my bad. But it's still vaporware.
