It appears that Dell will be selling laptops preloaded with Ubuntu Linux soon.
It's worth noting that Dell's CEO, Michael Dell has a Dell Precision M90 laptop loaded with Ubuntu 7.04 Feisty Fawn. Details about Michael Dell's computers are here.
Castolon LLC is now offering support for Ubuntu Linux on an experimental basis. The first few support requests we receive will be free. Afterwards, we'll phase in a small charge for each issue solved. Use the Contact form above to request support.
Of course, if you get Ubuntu on a Dell laptop, you'll get support directly from Canonical, the company the produces Ubuntu, and you won't need support from Castolon LLC.
