I did the same. I tried to use the Apple mouse for a couple months, I really did, but I felt my wrists turning into frozen fish and decided enough was enough. (This was the previous generation mouse where you needed to replace the AA batteries yourself, like a barbarian. Are the current ones shaped any differently at least?). Brought in my old Das Keyboard while I was at it. World of difference. And I don't feel any less cool, despite there being several physical buttons and a hole on the side of my mouse.
