I have actually purchased the computer with 4GB RAM (instead of the standard 2 GB) because I wanted to obtain experience with desktop virtualisation. Running a virtual Windows 7 within a Windows 7 with only 2.8 GB RAM appears to be pretty slow. The additional memory that the 32 bit OS would be able to use could improve my experience. I don't think I want to buy an extra video card now... BTW, Linux runs w/o any speed issue in VMplayer.
