Pros
Air2Web has a very casual dress code, lots of opportunity to work on interesting projects that can make a real difference to the companies bottom line. It's a small company that is well capitalized. You get to utilize new technologies and there's lots of places to add value to the products. Low turn over rate.
Cons
Company direction is difficult to predict. Lots of movement on a lot of different fronts without a "central theme". Sometimes too casual. If you are into/dependent on process, you will find it very frustrating, but if you thrive on driving fast with your eyes closed, it's impressive what can be accomplished.
