I've seen more than a few non-robot projects that use it.
Oh, and I'm AVR because of the free C/C++ compiler available for it. Might try a PIC someday, though.
+1 for a fantastic C compiler.
i still have to decide. For now i am using picaxe but for my next project i'll either switch to bare PICs (basic though, not assembler) or AVRs, not really sure which one to choose. I think it will depend on the amount of informations i find around the net.
I really like those picaxe-style datasheets that show all the commands you can use in one single pdf file, also found a similar thing for the PICs but still have to find them for AVRs. I'm not firmly settling down on PICs not because of the slower speed (1/4 compared to AVR) but because of the expensive compiler.
