There is a relatively new distribution called ION.
They claim to run both linux and window programs.
Never used it, so I don't know its quality. One thing:
It's only available on computers made by element computer.
See
http://www.elementcomputer.com/ -> ION
Even xandros runs crossover office , a window emulator
like wine.
Other than ION, you're probably best off running a window
emulator like crossover office, win4lin, wine, etc.
