The screen is very good, operates pretty fast with no lags, camera does a good job although pictures might get a bit grainy when there is not enough light.
The main downside(after using an iphone 4) is that it is harder to use this phone with one hand, but not impossible. It takes a while to get used to the button location.
In addition, battery is okay but not more than that - lasts nearly one day with moderate use.
1.price(this is relatively cheaper than similar phones on the market)
2.extra microSD slot(i listen to .flac or .apm format only, and I watch HD movies on it. I need lots of space)
3.removable battery(which means I can extend the battery time by exchanging it)
Overall a very nice phone.
