Hi I am a complete newbie and currently have a dual booting Vista/Windows 7 but I am desperate to put OSX on the AAO Can I delete Vista and put OSX onto that partition fairly easily? Also I have no experience with OSX how hard is the install using iatkos 10.5.5? I have changed the Hard Drive added extra RAM and swapped the Wireless card for the Dell OSX freindly card Thanks in advance for your help
