I'll wait for a mouse with that sensor xD. It's just incredible...
I wanted the AM but I waited for the Kana, the kana is a fail.
I went for the deathadder, because the zowie AM tracking speeds are a little bit low... then the G400 is free from path correction. I was going to get a G400 and I read this xD.
So again.... stick to the deathadder until a mouse with this sensor comes up !
