Woops!
Awesome images! Panther has been an awesome OS, Tiger doesn't look like it's going to add that much, but will be mostly concerned with streamlining existing features.
On another note, considering Apple's recent heavy handed approach to the disclosure of confidential information, a little more caution is warranted.
#1 It's a minor thing, yes, But don't reveal localization. If Apple decides to go on a witch hunt, flying the Union Jack in your menu bar, showing that your currency is the "British pound sterling" and documenting that you use the european time server isn't exactly going to widen the pool of people they have to search through.
#2 Make sure you don't display your friends' AIM SNs. The image poster did an excellent job blurring half the screenshots but must have forgot in one.
#3 For god sakes don't take photos of your submissions to Apple! All they need do is look through their submission database for one sent on 2005-1-22 at 13:05 regarding build 8A351. I don't remember if bug reports include your serial or not, but they will most definitely include an IP. Oy...
In any case, goodluck and thanks for the screenshots!
