Seems like a fine machine, just not for me.

I currently use a 15" MacBook Pro. If I went smaller, I would want something similar in size to a 12" PowerBook.

As others have said, the hard drive space is also an issue. I suppose I could move my media to some other device, but them I'd be dragging accessories with me all the time. I also do network troubleshooting, so need the hard-wired Ethernet port.

I am curious to see how you can boot from a DVD drive in a different device, especially a non-Macintosh device.

At the end of the day, my nearly two year old MacBook Pro (ordered shortly after it was announced about two years ago) is still doing the job for me, especially after I upgraded to a 250GB hard drive this past fall.

I pretty strongly agree with this. This is a really cool machine for certain people, but not for me. Now if I had an unlimited budget to get my wife a brand new machine it would be perfect. She is currently using a G4 iBook, and this would be even more portable, and she only uses one USB port ever. And it has never had its ethernet jack utilized.

The only issue would be getting CD's into iTunes, and the shared CD thing would probably be just fine.

I my self use Pro Tools and Aperture, and often have firewire and USB devices connected. I also need upgradable RAM and HD space so that I can expand when necessary. As far as the general computing population goes though, I'm probably in the minority (although that minority is a majority on a site like MOSXH).
