$10 is pretty expensive for a lot of applications. I bet that
processor also uses a lot of power and takes up a lot of board
space. If you've only got $2-$3 in the money budget, 200uA at
1.8V in the power budget, and 6mm X 6mm of board-space, your
choices are limited.
Besides If you can get by with 256 or 512 bytes of RAM, why pay
4X the price for a 1K part?
Besides which, the 8032 instruction set and development tools
are icky compared to something like an MSP430 or an AVR. ;)
[The 8032 is still head and shoulders above the 8-bit PIC
