Positives:
1x4 GB RAM installed, a 2nd 4GB module can be retrofitted. Other manufacturers use 2x2 GB, then you have to buy 2x4 GB, the original RAM you have lying around.
SSD installation done in 5 minutes.
Good Keyboard with Numeric Keypad
Stable, but you need 2 hands to unfold.
There is a good docking solution with OneLink.
All major connections to the unit without an adapter available.
Negatives:
The display is large and okay but extremely angle-dependent, which somewhat annoying especially in size.
With these new trackpads, Lenovo has the customer done any favors. Apart from the long pressure point, it is too far left position.
The battery life is indicated optimistic and probably more so a gag as the Labelling of 3.3 liters in a diesel. Of course, who always travels at a constant speed in a circle ...
Windows 8 has to be installed, then all updates, then 8.1, then all updates thereto. Right annoying if you times again touches the thing in 2 years. But ok, more like a Windows problem.
With SSD and 8GB now the device is safe well equipped for the next few years for all Office applications. Thanks to the dock owner can as usual sitting at a desk, but more often I catch them stop but in the living room or at the kitchen table, then with the wireless mouse ;-)
