What version of Windows Vista works best on a MacBook 2.2 GHZ, 2 GB RAM, 160 GB HD, I am going to set the partition size to 40 GBs for Vista and 120 GBs for Mac OS X Leopard. I know Vista is pretty bad, but I need to run some Windows apps that aren't supported over Crossover, and I am not going to buy VMWare Fusion or Parallels, just use Boot Camp. I want to buy a 64-bit version of Vista and was leaning more towards Windows Vista Home Premium. I don't give a **** if Microsoft wants me to use Ultimate or Business, I just want to use it on my MacBook and want to use the best one for it. Which one would you recommend? Does Vista support 4 GBs of RAM?
