I've seen so many people say they removed Win7 or mroe commonly Vista after a few minutes and reverted to XP. HOwever, I have a $600.00 notebook that absolutely flies along with Win7. 7 is a completely different animal than previous Win releases, plus you get the security and added functionality that XP lacks. Win7 is excellent with dual core processor management, which wasn't even available (wasn't an issue) when XP was released. It manages teh disk much better too, nearly a year now and I still don't have to defrag, even though I add and delete severak hundred gigs or mixed data each week.
Even with indexing and Aeroglass turned on, I have no problems whatsoever. I work with business apps and files, run it through my sound desk for audio mixing/engineering, run teh full Adobe Master Suite for web, graphic and print design, run two or three video editing apps (rendering speed is much faster than with XP), download craploads of TV shows and movies, and play FPS games like COD and MOH (granted I have to back off the graphics settings a bit due the the GPU but I can still get a decent frame rate and more than fair graphics).
Let her play with it for a while, if needed you can tweak thing but I'm sure it will work out, IF HP actually sold a compatible notebook with it.
