It would be much better if everybody created an ADC account (it's free) and posted the bugs at http://bugreport.apple.com
That way Apple will do something about it! Discussing it here won't be so productive. Of course you can discuss it but Apple should also know
All the bugs, in just one thread? Wow, need to reserve a server for this thread alone.
Here's my contribution so far (I'm had family visiting so I've only spent a short time using it so far):
D-Link Bluetooth dongle no longer works when plugged into my USB hub
Leopard installer hangs with 1 minute to go on PowerMac G5
On my third attempt to installing on a brand new formatted hard drive on the G5 I got a 'failed to install' with 27 minutes to go (haven't had time to look at the log).
I've just done an extended hardware test on the G5 and all is fine. The DVD goes through the DVD verification without problems.
