At this point it seems like these websites are placing bets between each other to see who can get closest to an NDA violation without actually getting nailed with one. HardMac has posted the latest set of (non-blurry, properly grabbed) screenshots of some hitherto unforeseen areas of Mac OS X 10.5 Leopard, including the Spaces and Time machine system preference setup panes, Mail.app stationary and a photo browser (which might make these iTunes and iPhoto library browsers
extinct), RSS feeds and setup, notes in Mail with todos and calendar settings, as well as exclusives of new Finder functionality (note the lack of brushed metal in the Smart Folder) and Preview features.
So far I'd have to say this is probably the most exciting set of screenshots as they are some of the most revealing of new features and abilities in Leopard. Er, I mean, a friend told me they look really great... check them out
while they're still live boys and girls.
