The newer Macbooks have a few things that I'm still on the fence about.
The new buttonless trackpad takes a bit of getting use to and I haven't used it enough to decide if it is progress or a step backwards due to Mr. Job's apparent button aversion. It's multi touch which is nice and more and more programs are now supporting multi touch.
(anyone remember the dreadful round mouse?)
The Glossy Screen only option didn't work too well when I was at the Apple store due to the overhead lights reflecting in it and making it hard to see. You can buy non glare films to put over the glass so this may be a none issue.
The new DisplayPort is on paper a step forward over the older DVI port but Apple has come out with their own connector that no one else in the entire world is using and there are limited adapter choices if you want to use anything but the new 24" Apple display. Also it no longer carries an analog signal so you will have to buy a breakout box converter if you need to hook it to something like a SVideo projector or something.
The new black backlit keys are much easier to see then the old silver keys.
