I was just about to send it back, which explains the large amount of Books at Warehouse Deals. Therefore, I had mine also.
Installing a Linux (Debian) turned out to be more complicated than I suspected, this is certainly the fact that I found after a long search found that the wifi chipset has a problem with the power-saving mode and thus regularly not working. Only when you issue this function tough driver works Wifi clean. The problem should also Windows users, according to the English help pages of Lenovo.
Otherwise it's just a more favorable Lenovo model. The non-backlit keyboard, does not bother me as blind-prediction and is okay. That only one USB3 port and no Ethernet is available, is unfortunate but acceptable. The screen resolution is okay for the price, if you also would like to have HD, but if I want to watch movies, I close the unit either way usually on to larger monitors.
Real plus is the low weight, the really fast disk and a remarkably long battery life when the monitor is not too light turns (> 5h). So overall a good laptop on the go.
