I have this device not report for 3 months in use and can hold up to the first 24 hours negative. The reason for the initial anger was Windows Vista. The operating system was not only very slowly, it left me with some crashes caused as: the Bluetooth Tongle has not understood at all with Vista. Ergo Vista ground and the good old XP. All XP drivers were available on the Lenovo website, but it took some time until the entire Werkl went. Since then, everything is going great. This part is very well made, nothing creaks and the speed for normal work is more than adequate. One must keep in mind that you are dealing with a notebook in the Netbook price range and if this is in mind holds the thing, first with 2 GB of memory, a good screen resolution and a processor of each atom in the shade is equipped , then the notebook is certainly a good grip. If one should imagine jeoch games without end or expensive image editing one time in 1500, - Euro class look. One star deduction is available for the Windows Vista.Man could certainly ask 20 Euro more and it deliver the notebook with Windows 7.
