This model looks to me like a really Plastikbomber and feels so well to. Very poor in my opinion. But I have the functionality tested anyway times. It falls on the this model very very long constantly loiters on the hard drive around. In terms of time, it makes no fun with it because to work. I then System Restore to revert to the factory settings started. Please do not ask how long this lasted, in any case, more than 5 hours. This capacity is sufficient for me in any case. Either the CPU or chipset, the hard drive and the RAM not powerful enough. In this combination, the model is not used productively for me. Since my smartphone's felt powerful. Since I can only return this model and recommend Do not continue.
