I have mixed feelings:
1) Although all my external devices have USB 2.0 as an option, I've always preferred Firewire (especially because I can chain devices without a hub).
2) I like the light weight of the new MacBook (.1 lbs lighter than my 12" PB). I'd be inclined to get the Pro though so I could have Firewire.
3) I don't really care about the graphics -- Intel Integrated was good enough for me. What I do care about is that the processor speed is lower for the dollar than it was before (see below). What IS cool is that 30" external displays are now an option for the low end with a dual-link adapter.
4) The machine is beautiful (can't wait to see it for real tomorrow).
5) I don't mind glossy. Between the iPhone and the iMac, I'm used to it.
6) I used to defend the value of a Mac because for at least two or three years they did provide good value. No longer. There is now a clear (and steep) premium for the Macbook and Macbook Pro. For portable use, it's just not justifiable to spend so much in the day and age of cloud computing.
7) The 24" display is pretty but I'll stick with my much cheaper Dell, thanks. A second power adapter to keep plugged in at home for the laptop is much cheaper!
In short, I'm happy I just bought a 12" PowerBook for 1/3 the cost. Until my iMac dies (which could be a while), and the price comes down, I can live without the new MacBook or MacBook Pro.
