I currently have a TiBook 550Mhz with a DVD drive, but I am really wanting a new 1Ghz Superdrive Ti now, but I think I'm going to TRY and wait on built-in bluetooth.
Faster Airport would probably be cool to, but it isn't essential.
As for USB 2, I don't really see the need. I've got Firewire (and soon Firewire 2) so having another high-speed port is kind of repetitive, since it's not needed for disk drives, keyboards, or mouses (I believe it's mouses when talking computers).
However, I do think Apple should implement it, if only so the lay person doesn't see that as lacking on a Mac. As USB 2 becomes more popular, people are probably getting USB 2 CD Burners and harddrives, and if they switch to the Mac, they should be able to use them at the full USB 2 speed.
I agree that the floppy is on it's way out, but I still use them, mainly for school where it's all Pee-Cee. I do like using disks, only because they are reusable and it is faster to put a small file on a disk, than to burn a small file on a CD. Also, a lot of the people I know don't have CD burners, so they will often times give me something on disk.
ALSO: Will there be Superdrive's (Pioneer drives) in the future that will burn DVD-RW's? I heard from someone that they did, but my boss confirmed that they didn't.
