Although I have ALWAYS said that whatever MS states as the minimum configuration, that you should double that, (IE. xMHz speed, better make that 2xMHz; yMB of memory, better make that 2yMB) I believe that the numbers coming from MS in regards to Win7 are in error. The reason I believe they have their inflated numbers (something no less than what they stated for Vista) is that they are trying to avoid the "egg on their face" that Win7 is not requiring a step-up in all hardware departments.

I am pretty sure that Win7 will work just hunky-dory of your laptop. Else I would not have suggested it.
