Love this!


What a purchase. I am pretty good with tech stuff, but a friend of mine who really knows hardware looked at the specs and thought very highly of it. The rest of my friends - who know very little about tech stuff - all fell in love with it as I did....

Display, speed, multi-touchscreen, sound, wireless keyboard/mouse, speed of delivery

None that I have noticed

Over before it started...


I purchased this item, refurbished, from the Lenovo Outlet; the features were incredible, and the price was unbelievable. Unfortunately, the item was dead on arrival - upon start up, I received the "Operating System Not Found" error.
