Summary: I really like this laptop. It is a good size, runs fast and the keyboard feels and works great. The only thing I do not like is the touch pad, you can hardly feel the edges of it so it is easy to wander on or off it with your fingers.
Summary: The best laptop I have ever owned. I found many are still under warranty which means you can get the Factory Preload DVDs free from Lenovo. If it has the orgional Lenovo preload, it will include Windows Word and Excell Starter edition built in that I found just as good as having Windows Office for most users...you can't get that anymore. Recommend the 1600x900 screen resolution...many have lower resolution.
Summary: I have been using this laptop for almost 2 years and I absolutely love it. It's light and fast, if I had just one complaint it's that I need more memory but that isn't that big of a deal as I have a large external hard-drive to save excess photos and videos. I have no idea why some of these reviewers have had issues, maybe they did not have good virus protection/firewall setup. I am using ESET NOD32 virus protection and it never bothers me and I have never had a problem.
Summary: As a working tool laptop proved to be excellent. Classroom keyboard with soft quiet keys, touchpad trackpad to control the mouse pointer, a flashlight to illuminate the keyboard in the dark make it very comfortable watching programming on a laptop. I note also of the shortcomings of the matrix of new laptop - I would like to IPS. And so the viewing angles Imagination is not amazing, the color quality is not particularly happy, although TN-ka is not the worst.
Summary: It does exactly what I expect it to do, and performance is above average for the price I payed. I preferred the T420 over the T430 due to the keyboard layout. The battery lasts about 7 to 9 hours but obviously varies depending on whether your just browsing or playing games. Although many claim it is a bit bulky, it is still quite transportable without it being cumbersome, although it is a bit bigger than other laptops.
Summary: While this was advertised as a used computer, it looked new and was set up for a new install of Windows 7 Home Premium. I've only had it a day, but this looks like a really great computer! Clearly faster than my other T400! 10Mb of RAM and a 64-bit operating system doesn't hurt!
