Summary: I bought this to replace a stolen laptop. I am not a fan of Win8 and had to search a while to find just the right combination of features to meet my needs. This one did not disappoint. Other reviews speak of screen issues etc, but I haven't had anything like than in the several months I have owned this one. I am not a gamer - so I cannot speak to the graphics quality etc.
Summary: I bought the Lenovo B590 to replace my wife's aging IBM T60 laptop. The T60 was running XP and had only 2G of memory. I don't want to spend the money to upgrade the memory and Windows 7 OS on this fairly slow laptop. If you don't have too high of expectation on a $430 laptop, this B590 would be fine for everyday basic tasks like email, word processing, and web surfing. I guess the letter B in the model number must be stand for Basic or Budget.
Summary: I bought this as a replacement for an 11 year old Windows XP machine for my 81 year old Dad. I chose this Win 7 machine as I believed it to be the easiest transition for him...and because I'm not yet a fan of Win 8. I worked with it about 12-15 hours over the course of a few days visit to get it to the place where he can use it easily. Compared to the 11 year old machine...this is a speed demon.
Summary: This is a nice little computer. My only wish is that it had the Word program. I also have some trouble with the cursor bouncing around. whether that is because I accidentally hit the pad, I do not know.
