So having weighed all options, I am deciding to go with Win XP since my MBP is a late 2006 model and will not be officially supported for Win7. I have already tried Win7 and it is giving me problems. I know all about the OEM vs Retail EULAs. That being said, I just have 2 final questions: 1) Does Win XP Home come in a 64 bit version? 2) Will this version of Win XP Home (OEM) SP3 work with my Late 2006 MBP if installed via BootCamp? http://www.newegg.com/Product/Product.aspx?Item=N82E16832116511 Thanks!
