You have to empty the Trash to permanently delete things (I get why, it's just an annoyance).
There's a workaround for this; it's about the first thing I did when I got my mac because I just hate the Trash. When I delete something, I want it to stay that way

.
To do it, you have to execute the following in Terminal (maybe as root, I'm not sure):
Code:
cd
rm -rf .Trash
ln -s /dev/null .Trash
An alternative, if you actually use the trash sometimes, would be to set up another folder as your black hole, with
Code:
ln -s /dev/null other_folder
and put it next to the trash icon in the dock (the downside of this is that there wouldn't be a shortcut for killing a file).
As for what bugs me in Mac OS X:
- The .mac thing. For instance, it can't be deleted from iSync, and it's really annoying for me to having it sitting there. Why the hell don't they allow it to be deleted? Also, the lack of an easy way to synchronize stuff with another mac without using the dreadful .mac. That's just an artificial way to create the need for it, because it isn't really necessary to do the sync online.
- The crippling. Many functionalities of the OS are crippled; for instance, the maximum of people you can share internet with, or the fact that you can only share one folder (all things that aren't crippled in Server... only server is way too expensive to get only for this things).
- The inconsistency in the default browser configuration. Why the hell is it Safari? It doesn't belong there, and Apple should know better.
- The inability of manually organizing the folders on iPhoto. Why is it possible in iTunes, but not iPhoto?
Still, I think the good of Apple and Mac OS X far outweight the bad, and I'm happier with my Powerbook running Tiger that I've ever been with any other computer and OS. I don't plan on switching back any time soon; but I expect this issues to be fixed over time.
