Leading Forbes' list of uber-cheap PCs (all under $300) is the $85 MicroClient JrSX from Norhtec, a book-size desktop that boasts (or perhaps doesn't) 128MB of RAM, a 300Mhz processor and a flash card-based storage system. Missing from the package are a keyboard, mouse and monitor
and audio. That's right, no audio. Anything with sound would probably make it crash, anyway.
Also making appearances on the list are the OLPC and the surprisingly beefy-for-$220 Microtel MCS7001. While all are astoundingly cheap, let's just say their unspectacular specs preclude them from popping up on my Christmas list.
