I bought a 21.5 base model iMac yesterday to finally replace my old Rev A G5 dualie. On my old G5 I was using Logic Express 8. Migration Assistant transferred it over when I set up the new iMac and I wasn't expecting it to run. But it does - and in Activity Monitor it's listed as Intel. WTF? Not that I'm complaining but this surprised me. Love the iMac, it's gorgeous and flawless and waaaaaaay faster than the old G5 beast. So nice.
