Timepass said:what I think hurts the USB ports on the Mac laptops is how they designed the screen lid and how it open. The design may look pretty but it end up destoring a ton or space that they could of put some of there ports in the rear of the computer.
Have the set up where they can use the back side of the computer things like vents, a USB or 2, Firewire and power normally all go there. Other things I have seen back there on others is things like the eithornet port sound can (I like that one on the side). Problem is in the design they cannt use th back side of the computer at all to store things like that. I personally would much rather have the power plug into the back of computer than the side.
Also that change would not change the thinkness of the laptop at all while closed. Just it would be a little taller while open because part of the screen is not going to dro down the back side of the laptop.
The TiBooks had almost all the ports on the back, which makes them harder to reach when you're at a desk, and makes the whole computer deeper because the hinge has to float above the ports.
