But it just got me thinking that we must understand these heuristics and not just follow them blindly.
I wasn't saying the OC did a bad thing, just thinking out loud about how "wait for the first point release" can be arbitrary since with such a popular software, you could read the feedback on various forums to see how stable it is.
If you're going to be having a major problem, chances are others will have it too. And if it's a minor problem that almost nobody has except you, it might not be fixed in the first point release.
So they mixed in a few small improvements and shipped it as a point release. It played well, I haven't seen any articles in e.g. computerworld that Apple finally fixed the security problem.
I agree that with such widely distributed software, browsing forums and news aggregators might well be as useful as waiting to see what's fixed.
PlugSuit, on the other hand, is SIMBL-compatible and uses a completely different method of injection. The author just needs to work around some new limitations introduced in Snow Leopard before it works with 64-bit apps. I would keep your eyes peeled for an update.
Right now I'm running a byzantine mess of a 10.3 upgraded to 10.4 upgrade to 10.5 and then transferred through 2 machines via Time Machine.
Either way, it pays to wait if you're risk averse. And I am.
