Up to 5cents now. Limited peripherals and no analogue channels makes them less use than a lot of other 6-pin micros.

Analog out can usually be obtained via PWM followed by a low pass filter. Analog input can commonly be done with a similar approach, short a cap, then let if fill up. Measure the amount of time until you read a 1 instead of a 0. Granted those are crappy analog options. However a slow 8 bit analog option is acceptable for many applications.
