When they introduced the Macbook in the keynote, my first impulse was to replace my 11" MBA with it. After I saw that it has no ports that are usable for anything without a dongle, I decided to keep my MBA.

Maybe next year. I'm pretty sure they will add another port in the next iteration just like they did with the first MBA. The display is very nice (checked it out in the store), but I never had any issues with the MBA's. The new keyboard sucks, IMO.
Come on, I'm 67, and can't wait to LEARN, the new Keyboard, these days, everything is in a Cloud, who needs ports, need more there are the MBA's,MBP, buy them! We heard this same diatribe, when

Sent the Floppy away,the CD Rom away,FireWire,etc.
Now, this brilliant piece of work arrives, and because it's "different" in Keyboard,in CPU, in ports, people here just can't handle it, see it for what it is, the future, of the whole line up, it's the minimalist view, using external sources for everything else. I'm buying the MBr with the 1.3 processor,and 512 SSD, and I will run my business with it, attend to my personal life,(email,photos,texts), and finish my Cookbook with it.
Point is, IMHO, people buy far more than they perceive they really need, this light feather of a Laptop, will be just what 70% of us REALLY need, for the other 30% there is the rest of the line up.(Please don't beat me up on the %'s)
Most of you are more computer savvy than I will ever be, you'll learn the keyboard, in a heartbeat, this IS the future, it's here now, EMBRACE it, cus everyone else will follow.."You do realize this Keyboard is already in the 13" MBP, and soon to be in the 15" MBP"?
Enjoy the fact that

Leads the computer cutting edge business, jump in to,this, the future, or move to other Apple products, or MS Surface, or what ever floats your boat, but realize this is nothing more than the death of the CD Rom, floppy drive,etc, done in one STUNNING package
Rant over!

I also think, this will be a complete fantastic success, with Millions sold, lucky us.! lucky Apple, for nailing it again, not for everybody, but enough for many!
