Mac OS X Lion: Should You Upgrade or Wait?

As of two days ago, GPGMail plugin doesn't work with Lion.

100% dealbreaker for me.

(And when it does, I'll gladly upgrade!).

Wait. Don't make my mistake. It really needs 3 or 4 patch releases to fix stability and performance issues.

Wait. Performance decreases are not worth the useless Mission Control.

Agreed, I'm holding off on installing Lion.

I'm having problems with USB devices and didn't have any with snow leopard. Hopefully after the first patch things will be much better ;)
