* DUAL SIM!
* Great audio quality!
* Good size!

battery life could be improved.

Agree with Mr. hamuyewa, power consumption is comperatively high, the trick is you have to upload the latest firmwware from Acer as well as the batch to improve battery performance.

I have a lucky one on hand without QA problem. Battery last for approx. 45-50 hrs with both SIM on as well as connecting to exchange server for email under stad-by mode.

Two Sim Cards and Standby at same time and the 1st Sim can be 3G. No other Windows mobile phone can have 2 sims, 2 standby.
Spb shell included for enhance interface.
size is quite compact. size is about right.
Plastic back gives good feel on griping
Good customer service

Power consumption is high
Not stable. sometimes hung
Quality control of manufacturing is not good. I tested 3 machines before I bought but all three machines had problem.
The one I bought, wifi was not work. I have to bring to repair and they changed a new one for me.
Cannot use gprs for sim2
cannot use sim application in sim2

Not recommend to buy.
power consumption is high and manufacturing quality is not stable
sim2 cannot use gprs
sim2 cannot use sim application (cause I use 1 card 2 numbers)
These disadvantages are very critical.
