Maybe it's a little bit late to review this one since Apple has launched the newer generation for Iphone which is Iphone 4, but I just got this beautiful gadget about 3 months ago from my Company. The reason is because we have to use Microsoft Exchange to communicate with internal colleagues in my Company. I can say that this gadget is awesome, in term of look and application. I admit that this gadget save my life every time when I caught in the boring moment :) such as in airport waiting for the delayed flight, traffic jam, or even when waiting for my wife shopping and meet with her friends.
The features are very rich, the sound and video output are awesome. furthermore there are so many application in itunes store that really really reliable to kill your time, game, tips, books they're all very entertaining. and the motion and gravity feature within the gadget is quite entertaining and useful. the response of the touch screen is outstanding, I guess this is the best touch screen gadget compared to any other touch screen gadget.
But I face some problem behind those great features. The battery is Bad, I have to charge at least 2 times a day since I have to always accessing email with this gadget, I can feel that the push mail still not as good as blackberry, I also found lost connection so many time, and you should be careful with that sophisticated looks. The black piano panel in the backside of the body is quiet fragile like other "black piano" surfaces, a scratch will be easily highlighted on this texture, so you have to use a soft case to protect the backside. I use Capdase soft case to protect it.
Overall, the product is great. Very recommended for you that looking for style and amusement.
