Didn’t get to use it that long. But the screen is really big and there is a lot of space around the keyboard. Like a TiBook, but wider, maybe 2 or three inches from the keyboard to the side of the machine on both sides. This means it probably won’t fit in my backpack sleeve as my TiBook barely does.
I have a 17″ iMac at work and there is a lot of screen real estate.
The keyboard feels nice. To me keyboard feel is important as it is to a lot of people, but it is also subjective. I just read recently some one who hated the feel of the Aluminum keys. I didn’t notice the material and like the feel of the key press. For reference I don’t like the feel of my iMac white extended keyboard. The shift key is unreliable. I like the keyboard on my TiBook though.
Didn’t see the back light, but I can see its usefulness.
What else? Mmm the hinge for the screen is like the iBook and I think that is better. And all of the ports are on the sides, which is good if you connect and disconnect stuff a lot. Might be a problem if you leave it parked.
I could sure use a faster AirPort, but that requires a new base station as well.
Those are my thought on the 17″ hope that helps.
