Well, I can copy a DVD to hard disk, burn a copy, watch an NBA game via digital satellitle, have multiple streaming videos running watching several live streaming broadcasts simulatneously, manage online accounts with multiple explorers running, type answering email, search my JPEG files on storage drive, crop a funny pic in Elements, save to Word, do a search, etc. ALL at the same time with little lag or hesitation noticable. It's very cool.
I demand my OS be committed to RAM. If Superfetch version 2 Pro is willing.
