Good point. I ordered it for my Imac Intel Core Duo...it uses laptop/notebook memory as well. For what it's worth, I noticed that Outpost.com had the Parallels Desktop for Mac (enabling you to run Windows XP from OSX on Intel based Macs) for $39 after $20 rebate, which is also a pretty hot deal, cheaper than I've seen it anywhere else. I ordered this as well. That's why I wanted to upgrade to 2GB.
