Here's a video I made just now. It's actually performing better than most times, which is saying a lot...

Great video. Your experience is along the lines of mine. I felt the in store model was a bit better though.
Regardless, I think the new MB is literally best suited for facebook, twitter, taking notes in class, watching 720p video, facetime chats, etc
I believe there is a market for the above. In fact, I use to use my PC for pretty much just the above. I think college students, and especially high school kids with rich parents would love it.
Also, the elderly would be a great market, if for whatever reason an iPad isn't enough.
If you have serious work to do, even if it's NOT video editing or anything demanding, I would pass.
The MBPr just feels like it can handle anything I throw at it without *ANY* lag, slowness, wait, nothing.
Everything just *snaps* the instant I click on it. It's almost like as soon as I think "I need to check my calendar" it's INSTANTLY popped up.
