You guys don't know what Bonjour is? Here you go!
Valuable piece of software that I have on all my windows machines.
I digress; Quicktime update? They plainly gave a link in the update pane, that explained all of the security patches, fixes, etc., if you were so inclined to click it.
iTunes installation problems? Not here.
Sorry guys you had issues; support forums are there for your convenience when you do have an issue... I'm happy Apple provides and supports them. (It's also their way to monitor and make things better). A forum with a few hundred cases of problems is VERY good, considering millions of installations. Many times, it's some third party this or that causing a conflict, and there is just no way to ever anticipate everything. It's very helpful having the support forums there, to vet out and help us fix those special issues when they arise. I know they've quickly gotten me out of a jamb on occasion.
