Me too and for almost exactly the same reasons.

I do have an IBM KPD8923 which has an integrated track-point mouse (between the G, H and B keys) I use. However, it doesn't have anything like a mouse wheel so I still have to use a mouse.

For my main developmental computer, I still use the old IBM Model-M keyboard. There's nothing quite like a buckling spring:
