The SL300 is a new 13" laptop model from Lenovo marketed towards smaller business that desire ThinkPad quality without the price tag often associated with it. Built to be fast and as full featured as the T Series, the SL300 is also based on the new Centrino 2 platform, using the new and improved Intel X4500 integrated graphics chip. Unlike the others in the SL series that utilize earlier generation Core 2 Duos and DDR2 ram, the SL300 includes the same high end components used in the latest T series. It also contains an LED backlit screen, putting it on par with the likes of the X300. Similar to the others, it also has the option for a discrete graphics card, allowing for better 3D performance. Starting at 4.6 pounds, the SL300 is an all around powerhouse performer on par with Lenovo's T offerings.
