I was at CompUSA tonight looking at the Macs and noticed something. The iBooks and 12" Powerbook didn't seem to have the feature where you can tap on the trackpad to select items. The 15" and 17" had the feature. Were these just defects or do they not include this feature on the iBooks (12"/14") and the 12" PB? BTW: I had a close encounter with the 30" ACD hooked up to a dual 2.7". That thing is so.................mouth salivating.
