One thing that I don't understand about that chart is how they have only 24 passengers/vehicle? From my understanding, that's not per car, but the entire train. Also the energy/passenger shouldn't scale linear. A train should be able to pull twice the number of people with little increase in energy output.
Correcting myself:)
Everytime you rip to mp3 (or any lossy) format you will lose more data because the compression is lossy. If you start with a wav file, compress it to mp3 you have lost data, so when you uncompress it the wav file will be different. If you then recompress, it's going to apply the same lossy compression to this new wav file, not to the old original wav file.
So with each compression you will lose data.
I'm not sure, but it would be easy to test this. Start with a wav file and rip it twice to mp3 format and diff the results. Also to do your test, you need to rip the mp3 with the same tool that was originally used.
It wasn't just the UI and hardware either. Buying music on the itunes music store is so simple that everyone can use it. Also if you have one computer, syncing your iPod needs no user intervention. (syncing 2 computers sucks tho)
OS X has its own style of drivers, completely different than any other operating system. It uses c++ to code their IOKit drivers, which make it easy to program, but not portable at all.

Sweet - I've been burned by this a bunch of times. Very glad to see it fixed - now to check and make sure it really is fixed :)

The problem is that the difference is all in the feel. The fact that they last so long doesn't really matter.
They assume that the people buying the keyboard had (or at least typed on) one of the old ADB keyboards and remember how much they liked them.
