There have been many reviews of Lenovo’s slim new X300, but if you still are not sure if you want to buy it check out some benchmarks and video courtesy of NoteBook review. Lenovo’s X300 did not surprise us much, the X300 trailed both the Macbook Air and Sony Vaio TZ in processor tests, but won for overall system performance. The video (after the jump) shows off the X300 from every angle and compares it to the Thinkpad T61 and X61.
