I tried a new HP laptop G62-347 NR, which features an AMD Athlon 2.2 GHz 64bit dual core processor with Ubuntu.
My impressions of both the laptop and it’s compatibility with Ubuntu are positive.
The keyboard is a bit awkward. Usually the ‘Ctrl’ key is at the bottom left. Here it’s left but one. Gets in the way sometimes.
Other than that, it’s first class stuff. Wide screen, and flawless with Ubuntu.
