As much as I love my brand new Powerbook, I have to install VPC to run some WinXP only programs as my situation requires. I'm really worried that it will slow down my Mac big time. I have a 1.25GHz Powerbook G4 with 512Mb of RAM, which I'm planning to upgrade to 1G or even higher. And I will have to install the lastest VPC WinXP. My question is, with the stock spec, will VPC totally kill my Mac? What kinda performance can I expect with 1G+ of memory? I won't be running too many applications on Windows, just 2 or 3 simple programs which won't require too much performance. Please help! Thanks in advance!!
