Sun Microsystems has partered with OEM builder, Microtel, and now machines that come preloaded with Sun's Java Desktop System (linux based) are being sold at WalMart starting at $300 for a PC with no floppy or monitor. You may remember a similar thing was/is being done by Lindows, no doubt Sun has more resources at hand for this projects... budget priced laptops wouldn't be a bad idea either if you ask me.
