Should I still support IE6?

The recent traffic statistics from both Shiroyuki Studio and Primal Fusion show me that there are quite a lot of users still using IE 6. This is very amazing but I really hate the fact that many people still use it and I have to some how tweak a standard code to an IE-compatible code. Arrrr!

In my opinion, although I hate it, I still have to support it until Microsoft ends its IE6 support. But I don't understand the reason people still use it since now IE7 is safer, faster and more compatible to the standard coding than IE6 (but still worse far beyond the other except Opera). Moreover, IE 7 is now available for everyone who even run a pirate-version Windows XP. But I believe that the majority of the users are not able to upgrade their web browser. Sadness.
