I have for the last 12 days, and this was after using an iMac from years back which processed everything excessively. Right now my swap usage is 640 MB. Worth mentioning, I am returning it tomorrow to get the latest offering. Probably in the same setup.
The last part isn't true. I've got the bottom priced 11" and being an entrepreneur I use it heavily for design. My only issue is the memory. After CS5 and a couple other programs I was down to 10gb.I'm 80% in front of a big cinema display but even working on the go its great. Photoshop too. My usual is itunes, mail, 5-10 safari windows, Photoshop, Illustrator and no spinning wheel of death. My experience of Apple is nearly 10 years and came from a 15" MBP that died.
If you're questioning it, go for it...
