I needed to upgrade to 10.5.3 sooner or later (I suspect the iPhone may need 10.5.3 - at least at launch time), but I'd intended to wait until it was absolutely necessary*.
I installed last night because I was enthused about one feature that promised to be of immediate value to us -- time limited child use.
Naturally, it doesn't work quite as well as I'd hoped ...
.. Since my original post I installed 10.5.1 and upgraded to 10.5.3. I discovered the shortest possible setting for time limited computer access is 30 minutes (per day).
I need a range where the low end is 10 minutes.
Sigh. Apple engineers need more children.
I also don't recommend regular people install an OS X update to an existing system until the DVDs actually ship with 10.5.3 or later. My install experience was unsettling...
Sigh. No Apple engineer should be allowed to work on parental controls unless they at least one child between the ages of 3 and 13.
I wonder if anyone has a hack to change the low end setting.
* Even 10.5.3, the 1/2 GB patch, has significant video issues on some relatively recent machines. Apple OS updates are also very expensive, since they may require replacing a range of software and peripherals. I'm still testing which of my things work with 10.5.3, I know that some apps that broke with 10.5.0 will more or less work with 10.5.3. One nice thing about 10.5.3 is it feels "smoother" on my Intel MacBook than 10.4.11. So it's not all bad.
