Years ago I used to have a Samsung Wave, which I could not convince. Then came the Iphone 3, then 4 and I thought I would never want to have something else ... until the update on IOS8 me a better informed: only extremely high battery consumption, no troubleshooting by Apple. Instead of help and support of the trial, yes veritable urging me something new, expensive to sell, although my machine was in itself tiptop ok - no thanks! And then this device came here and I have never for a moment lost something compared to the Iphone, quite the contrary. The display is much better, the response times are much faster, handling 1,000 times thoughtful, I am thrilled by AZ! And the price is "in passing" still super :-)
