Bought an inspiron on dells refurbished site for half nothing but it came with Vista. I never tried Vista but have no interest in leaving XP, which works grand. Dells site doesn’t have many XP drivers if you enter inspiron 1521 and it took me agggess on the Google to get video drivers for the inspiron 1521 graphics card. Figured out eventually that the XP graphics card drivers on the dell site for the latitude D531 work for it
Interesting was the google suggestions when I entered ‘inspiron 1521′. One was [inspiron 1521 ubuntu] and another was ‘inspiron 1521 xp video driver‘ both with loads of threads and blog posts as you could guess. Think vista in trouble alright.
