I saw this great bit of news over at BBC.

Microsoft plans cut-price Windows

Microsoft is to launch a low-cost version of its Windows XP program to try to halt the rise of rival Linux software.

...Microsoft's new software - dubbed "XP Lite" - will feature lower resolution graphics and limited options for networking computers together.

It will also limit users to running three programs concurrently - a far cry from the full version of XP, where the only practical limit comes from the speed of the computer and the size of its memory.

It will be available initially in Thailand, Malaysia, Indonesia and two other as yet unspecified Asian countries. [BBC News | TECHNOLOGY]

So let's see, since this is supposedly to compete against linux let's compare. Linux gives me no real restrictions as far as how many programs I run and what graphics modes I can use. And with XP Lite I can run three programs.
