I've completed a lot of projects with 8051 derivatives in the past (Dallas and Atmel mostly), but I am designing new projects with ARM Cortex-M3 chips from NXP. More speed, more memory, more peripherals, better watts/MHz, and decent free tools.

The bigger chips have dropped far enough in price that 8-bit uCs have almost lost their only advantage besides code compatibility with old firmware. I did recently use a $2 8-bit PIC when cost was the prime concern.
