This device is brilliant (and I'm here not been paid by Amazon). It's very fast, needs little electricity and turns only in a standby mode in which the device is used at any time, and still keep the Beátterien more than five days of standby from. Switching between programs work without bucking, synchronize it with Vista worked great and the device is light and slim. I also enjoy the keyboard and the touch screen and voice quality as with other handsets also, the other person is understood well and background noise do not bother really, there are certainly better of the voice quality of her but for the many useful functions I find it just great.
