I have a TS100, the fact that it sets the temperature to 150C when it's been still for a while and back to the work temperature when you pick it up is pretty useful (it also turns off after it's been idle for long enough). Its only flaw (same for the TS80, same for the Pinecil) is the tips that are outrageously expensive (Hakko compatible tips are ~$5, TS100 tips were ~$10 a piece last time I checked).
Also, a soldering station will tend to have a microcontroller inside if it has any sort of decent temperature control and digital display (you can even DIY - there are lots of controller kits that use Hakko tips out there); the Pinecil (and the TS100 / TS80, etc.) just has the brains built in for compactness and the aforementioned accelerometer goodness.
