Macs aren't for productivity, they aren't for Enterprise if you aren't a designer, and Office 2011 is a joke. Thankfully MS is finally coming out with a new Office finally.
2008 was a fine time to buy a Mac. And I don't believe anyone called them under powered, if you need a laptop with 16gb of RAM to do design work, get a MBP.
Hardware is good, Apple store support is good. No argument there. They're just lagging behind at this point and it's getting more obvious every release cycle.
