This isn't true...I have an old 1.4 Ghz Celeron (circa 2002) laptop with 512Mb RAM (an old one too weak to run on our corporate (school) network, but I use it as a browser. Installed Windows 7 on the machine tonight (+ Norton Internet Security 2010) and it boots in under a minute to the desktop. IE is much more swift and responsive. Not anywhere near as good as my Core 2 Quad machine in the study, but beggars can't be choosers! Settles on 390Mb RAM use. XP driver for my wireless slot-in card worked fine!
