Emacs on Mac OS X - To Alt or Command?

It's official. I love to hate Emacs on Mac OS X. No matter what I do, I get a thorn in side. When I try to write \ using Alt + Shift + 7 I get errors because Alt == Meta in Emacs. If I bind the Meta to the Command key I circumvent that error. All is fine. Till I want to use Meta-Tab. Now I'm suddenly trying to Command-Tab away from Emacs into some other application. I'm furious at the moment, could anyone help me solve this problem? I would prefer it if I could have Alt as meta, not install aquamacs.org and not use the fn key. *Oh, by the way, I use Swedish locale.* **EDIT 1:** First solution: add (global-set-key [C-tab] [M-tab]) to ~/.emacs. This will tie the Meta-tabto Control-tab instead. Not what I entirely wanted, but should work.
