Get your facts straight, or use one before you post uninformed drivel. I had a late 2008 15" MBP, with a 2.66 Core Duo, dual video, and 8GB of RAM. My new 2.13 MBA with SSD is sooo much faster than the MBP that I'm still in awe. Everything from browsing, to photo management to startup to word processing to VMWare is super fast on this thing. Heck, I even ran Autocad on it to see how it performs. Very impressed.
It's not about "Raw specs." It's about user experience.
Agreed. Don't fall for the megahertz-myth. That 2.13GHz Core2Duo will be much faster than a 2.66GHz Core Duo. In fact, that 2.13GHz Core2 is going to be faster than a 3.2GHz Pentium 4. It's more than just the number of cores, too, it's cache size, memory speed, etc. It's true that it's the slowest Mac right now (if you popped an SSD into everything else that is, the SSD makes it blazing fast). With the SSD the MBA "feels" faster, but like you said, that's kind of the point. I'm sorry, but if your trying to do enterprise level productivity, like 3D modeling or high resolution image manipulation, on an 11" notebook?
People need to realize that there are different markets out there. Apple still makes the Macbook Pro for those who need portability mixed with productivity, and the Macbook for those who need similar performance but not as many features. The air, is for the light to moderate Mac user who wants ultra-portability mixed with lightning speed in most things. Honestly, there's probably little a MBP can do that a MBA can't do (besides physical limitations, like a firewire port et al), albeit the MBP would be quicker in CPU intensive stuff.
The negativity is silly, I've said it before and I'll say it again, "Then don't buy that!"
