The Direct2Dell blog has a post about what will and will not be included in the upcoming Linux machines from Dell.

I found this particularly interesting:

For hardware options not offered with this release, we are working with the vendors of those devices to improve the maturity and stability of their associated Linux drivers. While this may not happen overnight, we do expect to have a broader range of hardware support with Linux over time.

This is good news. More driver support for Linux, fewer issues for new users to deal with. And Dell gets to sell a few more computers too.
