Lots of reviews here:

Pros:
- 0-60 in 5.8 seconds (can vary depending on the magazine that test drove it)
- I like the exterior (looks more aggressive and sleek)
- Light (~2,300 lbs)
- Warranty (always nice to have)
- Cheap to maintain
- No-hassle soft-top (one pull with arm gets it up and down while driving - less parts to break down compared to a powered top like the Boxster's)
Cons:
It's not a Porsche
Probably less roomy than the Boxster
Only one trunk
No glovebox
4 cylinder, less hp/torque but weighs less
