Leopard so far
I’ve upgraded two Macs at home without issues during the upgrade. My work MBP is still running Tiger and probably will be for quite a while.
I’ve had issues with Time Machine really dragging down system performance until the first complete sync was completed. For some reason the first synchronization failed for several days. My complaint on Time Machine is that there is no immediate link or callout for viewing its log. There should be. I assume it is someplace in /var but I have not gone there yet.
Terminal is a big improvement.
XDMCP seems broken in some way. Akthough I can connect to my Ubuntu box, the keyboard doesn’t work now on the login screen. Ouch. The old trick of switching the keyboard to extended layout has no affect.
Lack of Java 6 support is of course just a shame.
Overall my impression is that performance sufers just a bit.
