It's funny ... Once you go Mac you want to go Vista. I have been following Hans Verbeeck's adventures trying to get Vista running on his Mac Book Pro. Last week Bart finally got OS X running on his standard PC. He posted some screenshots and videos.
Yesterday I installed Vista Build 5536 (Pre RC1) on an Intel iMac. I used the recently updated Boot Camp 1.1 to create a Windows partition. After that the installation was a snap. No more need to delete the EFI partition.
Next steps are the drivers and of course ... SQL Server.
More SQL Server on Mac comming soon...
