Cons so far, about half a month after purchase:
- Seems not to have a camera zoom function
- Very little built-in storage (less than Samsung Galaxy SII, for example)
- Usual Samsung proprietary USB port
- I'm not thrilled with Samsung Kies software for updates and PC interaction
On the whole, I'm very happy with it. Pros:
- Takes pretty pictures
- Skype works well, sometimes camera seems to go to sleep if you don't move around much
- Has a normal-sized headphone slot and doesn't need special headphones to receive radio
- Fairly easy to use interface
- Nice size for normal / small hands and pockets, although doesn't really work for one-handed texting (for me)
- Audio quality on calls is good, i.e. it works as a phone ;-)
Overall, I'm very happy, although as it's my first smartphone there's a predictable jump in features. The Kies software really grates in comparison to the ease of uploading pictures from my old Nokia, though, and I haven't yet spotted how to make this phone "visible" to Windows Explorer so as not to need the software so frequently.
