NewMexiKen installed Windows Vista (Release Candidate 1) on my iMac today. There are still a few tweaks left, but both systems appear to be working fine. All-in-all, including the repair of an unrelated disk problem, it took less than 90 minutes.
Vista is real purty on the 20-inch Apple monitor.
Update: Some small problems in Windows with drivers and software, partly related to increased security in Vista. Just bugs that needed workarounds. Windows quite fast on iMac with 1GB RAM. Windows partition using only 10% of iMac hard drive with room to spare for software.
I put Windows on the Mac because I have a couple of Windows programs without Mac equivalents, one important to me. With free software (BootCamp from Apple and Vista from Microsoft) I’ve now got six more months to wean myself. (My copy of Windows Vista expires June 1, 2007.)
