GSM Arena reviewed the 8310 smartphone from Qtek, it retailes for about 400EUR and has lots of features, here's a snip from their review:

Qtek 8310 is a smartphone or, in other words, a device based on a mobile phone, which features OS and the functions of a pocket computer. Qtek 8310 works with Windows Mobile version 5.0. The device is meant exclusively for work. There is no objective reason to buy Qtek 8310 or similar types of smartphones, unless you need to organize your time or you have hundreds of contacts, or you have to have constant access to the internet. However, if you are interested in at least one of the latter options, then take Qtek 8310 into serious consideration.
