I've been searching for the right analogy to show ratings and number of reviews. Both variables are important - a few positive reviews shouldn't have anywhere near the impact of a large number of negative reviews.
So I did a little experiment: For some major GPS manufacturers, I plotted both the number of reviews and HowItSucks (HiS) rating for Jan - Nov 2007. The results are pretty interesting:
- Garmin GPS units really don't suck
- TomTom, Magellan, and Mio units kind of suck
- Mio's have risen in popularity in the 2nd half of 2007
