I work with the Prop quite a bit. My applications are mostly related to using the Prop as a multiprocessing MCU, rather than playing with the multimedia aspects that a lot of people are gaga over. One of my more recent apps was an autonomous roaming robotic system incorporating an RF telemetry uplink, GPS, an electric compass, and an accelerometer. I built it using several PICs initially, then rebuilt it using a single Prop - actually, only 6 cogs out of the Prop. Individual PICs can probably be clocked faster than a Prop. The PICs also have a better selection of internal peripherals, whereas the Prop is really geared toward maximizing I/O lines. The Spin language (the Prop can be programmed in Spin, or assembly) is fairly simple, but it suffers from being indentation-sensitive. I'm not a big fan of artificial, arbitrary syntax, but Spin is pretty easy to learn. Also, the programming software is free, and the required hardware is pretty cheap. The Prop can also boot entirely from an external I2C EEPROM. I'm still waiting for Parallax to release a Prop development board, and a Prop with more I/O lines, but otherwise, it's a great platform. If you have a specific question, ask away... BTW - unless I missed something, the Prop is not related to the SX.
