Overall I found this to be a balanced review, and an interesting read. I've used Linux exclusively at home for the last 10 years or so until buying a MacBook Pro about 6 months ago, so I don't think I have any particular . That said, I wanted to comment on a few things you said: You complained about iTunes' "inherent desire to rename and move your MP3s into new folders". You can turn this behavior off simply by unchecking two checkboxes in the Advanced tab in Preferences. In fact iTunes used to ship with these options turned off, but apparently Apple found that enough people WANTED iTunes to manage their music files that they started making that behavior the default. Your comments on iPhoto in this respect are also incorrect. In the advanced tab of iPhoto's preferences you can uncheck the "Copy files to iPhoto Library folder when adding to library" option, and it'll leave your files in their original location. Also, even if if you have this option checked, it still stores all the images as separate files with their original names, and just organizes them under its own directory structure, so I'm not sure what you meant by saying " in Leopard, [the iPhoto photos are] stored in a pseudo-file that is somewhat inaccessible to other programs and the file system itself". For OSX movie players you mentioned QuickTime but didn't mention DVD Player, which is pretty nice and is also included. You're correct that both of these players will obey DRM restrictions, but mplayer is just a "port install mplayer" away from being available on your Mac; you don't need Linux for that. The fact that OSX doesn't come with a Bittorrent client already installed seemed too trivial to even mention, let alone label as a "major drag". It's kind of like claiming in a car review that one car is better than another because it includes an air freshener right off the showroom floor. Just google for "osx bittorrent client" and you'll find a bunch. Personally I like "Transmission". Other than these points, I liked the review and found your comparisons interesting. Thanks for the review. »
