First of all, the tablet itself is to say that this is a very fine instrument. Very chic, processing my device I find excellent. It runs reasonably liquid (you should not have such a device compared to a notebook with i5 and SSD).
Although the battery has no 15h, but 10 definitely. Just do not leave for too long in power saving mode, the device, as it is also relatively uses a lot of power, so if you know you need it for 2-3 hours not simply shut down and then the battery at the next start is still as fully like when put away. The start is by the way also pretty fix, so it is not really necessary to use the power saving mode always. In my case booting the part in less than 15s.
So, now time for well-known problem with the Sim-LTE module. Unfortunately, I am also concerned, because even telecom cards are apparently not recognized and not only from Vodafone. I tested it with a Sim from O2, was not an issue, ran super. I'm waiting now to a final solution, because of "really miserable" Support from Lenovo, one of which they even served up lies, really no good at all. Currently, the solution is to buy the device and send it immediately, so Lenovo can import a firmware update for the LTE.Modul. But honestly, who buys a device that he has the same email only once in the repair ?!
So I'm waiting on whether it is a driver may patch as a software solution, which you can import itself. Otherwise, it will eventually be returned because there are no alternatives (as a unit) for me.
A word to the existing included Keyboard: The keyboard works great on all BT enabled devices, both PS3, as well as mobile phone, laptop, etc ... It can be super tap it.
But honestly, I buy a tablet to use it probably mobile, right? Why do I need a keyboard that me more hampered than "happy" for mobile use? It is now not just that you can only ever use the keyboard if you have a table. To make matters worse, they have to also still somewhere "park" when you take the device in the hand to read, for example, or just not a table is available. Since Lenovo has not thought about it.
