Vista OS

I'm thinking of getting myself a Vista Home Basic OS for my laptop. The Vista Starter OS that came with it seems to simply not be sufficient for all the things that I do. The Stater pack only allows three programs to be run simultaneously. It's quite irritating trying to open an application, only to find on the screen a pop-up message saying that I cannot do so unless I close any one of those currently running. haayy... I just hope I have enough money to buy me a licensed Home edition..
