The unifid UI is cool too though i would have prefered it was a choice between the Mail.app and iTunes interface i like the white one better.
It's silver when it's the active app and white when it's in the background, so technically your wish is granted.
Coverflow in finder is a brillent idea i have about 300 files in my site directory that can be difficult to sort though without a little help.
Remember that unless those images are big, they'll still be hard to see even in Coverflow. Therefore many images on a website are sometimes quite tiny, and will still be tiny when you browse through them (or horribly pixelated).
Also from what i have seen Leopard is a lot quicker than tiger but tiger is already pretty fast though not as snappy as Windows XP but a lot faster than Vista.
Depends what systems your running really doesn't it.
Time machine would be great but my USB hard drive has been killed by the 10.4.10 upgrade so i can only access it form my 10.4.10/9 machine that has the .9 usb stuff tacked on that i was unable to do to my macbook.
There's quite a chance that your issue will be fixed, however you should be using firewire for backups anyway, it's a lot faster.
Safari 3 looks like a nice incremental update it sorts a lot of problems with Safari 2 such as support with my sites WYSIWYG editior, and the inline search. Unfortunitly i can't use the beta just yet as it has messed up yahoo and msn making them annoying to use with yet no update form apple to resolve the problem yet. (edit installed the latest beta of safari 3 on my macbook it now works well, this may or may not be because of yahoo beta 2 though)
You'll find those issues you encounter are more of MSN and Yahoo's fault that Apple's. The services you can't access have always been low on the compatibility list for those companies, that's life, send them complaint, don't misplace your blame.
And the changes in iChat are pointless without msn and yahoo support. I have over 100 contacts and not one of them use AIM its kinda shunned here.
Many people in the US use AIM instead of MSN. It's very common and works quite well, if you have friends with macs, then I'd recommend just getting a simple AIM account and trying iChat's text, audio and video based chats. They really rock, and you can't even compare them to MSN or Yahoo.
MSN and Yahoo support in iChat isn't something Apple can just add, it's not their call, it's the other two companies, both of which I'm sure would be against the idea, or charge significantly for the ability.
Instead of complaining about how useless iChat is to you because you don't use it, try complaining to Microsoft and Yahoo about supplying decent IM apps for the mac.
It's possible Apple let 9A559 be GM but will have a d/l update ready the day Leopard ships so essentially the first version of Leopard is 10.5.1.
Updates to Leopard, just as Tiger, are helped along with the ADC community. If Apple was testing a 10.5.1 update already, it would of been seeded to developers and we'd know about it, due to the leaks they have.
