There's no problem in waiting for the first update. It's smart if you have sensitive files on your internal drive. Me, I'm free-spirited and willy nilly with my internal drive. The external has the few sensitives I have. But still, I'm hoping to see 10.5.1 soon too. Some people were expecting the first update to be on or near the day of release because they apparently rushed golden master out, but that's just silly.
I wonder if Apple would've delayed releasing 10.5.1 a couple of weeks even if it was ready on the day of leopard's launch in order to avoid any bad publicity. I can imagine reviewers spinning it in a bad way, like "Although leopard is a great upgrade, it seems like it must've been rushed because the first thing that happens when you run leopard for the first time is it tells you that you should download an update. That makes me wonder if leopard is only half baked, and makes me wonder if there are major bugs lurking just under the surface."
we must continue to wait for some issues to be solved that should have been fixed weeks ago.
Which issues are there? I've heard a lot of gripes about people not liking the new functions like the 3D dock, stacks replacing dock folder pop ups, the transparent menu bar, and to some degree the firewall. But I haven't heard about any "issues" in terms of problems that I'd expect to see in an update. Which issues are you referring to?
