This is one of the best 'issues' that people had with Mac OS X in the beginning. 'Ah! Put my Trash back on the Desktop!' they were screaming. And I, too, thought it was in the wrong place at first. But I suddenly noticed that
a) I don't use it that much, really. I always hit Cmd-Backspace instead.
b) If I want to use it, it's much easier to find now, and I have things I actually *need* on my Desktop. It *belongs* in the Dock.
And it's like that with more than just the Trash. Things like what's in the application's menu and what's under the Apple menu. The way Mac OS X handles the elements feels much more natural to me, once I'm 'converted'. Of course, it's difficult to get rid of old habits, but it only takes _some_ time - and Mac OS X helps you, because the things are where you would expect them, if you hadn't used Mac OS 9 before.
