In answer to the original poster, yes. When I got my N900 I had a good root through all the particular available developer workflows (Pluthon, Scratchbox, MADDE, even Vala) and I've decided that MADDE + Qt is going to be the thing for me.

I had varying levels of success with sorting out various Python dependencies, but I think I was unluckily in the middle of various release cycles so it wasn't easy. In the end I found Qt 4.6 most attractive, and I'm more a C-style guy than Python anyway. (I was/am working on a London Tube Map application.)

Very shortly after, I totalled my device by accident, so after reflashing thought I'd wait for everything to settle down and align a little so my toolchain was more stable before I began again in earnest. I'm fairly sure that wait will soon be over.
