It's got 1 gig with win 7 starter, I may upgrade it to 2. IE just seems to run slow on it while Chrome runs great. I just grabbed the firefox 4 beta so I may just end up using that if it runs as good as chrome. Of course I'm so used to using Firefox that IE may be running like it usually does.
Defintely upgrade to 2 gigs of RAM, it's cheap and easy to do and I think things will run snappier for you.
