Last year's winner in this category, the Nokia 770, has a younger sibling, and, as oft happens, the kid takes the cake. Nokia's N800, the follow-up to the 770, is smaller, lighter, better-looking, faster and has a larger brain.

Tip: Is my hardware Linux-compatible? Find out here

Tuesday, 14 August 2007
Deciding whether a particular computer is a good candidate for installing GNU/Linux can involve a nightmare of details about hardware compatibility. Nor is assembling a custom computer on which to run GNU/Linux any easier. In both cases, you need to evaluate video cards, sound cards, printers, scanners, digital camera, wireless cards, and mobile devices for compatibility with the operating system.

Tuesday, 31 July 2007

Wednesday, 18 July 2007
In the last two months I've been traveling a lot. During the same period my main desktop computer went belly up.

However, my main PC at home utilizes a 64-bit version of Ubuntu 7.04 Feisty Fawn, and Virtualbox didn't support 64-bit OSes -- until this month.
