Over the past year I've had the opportunity to review nearly half a dozen Lenovo notebooks including models from the consumer-level IdeaPad line as well as the business-oriented ThinkPad series.Living up to its reputation, I've generally been pleased with Lenovo's overall build quality and performance. The recently reviewed IdeaPad U260 was a real work of art and excelled in nearly every category except for one -- it narrowly missed Intel's Sandy Bridge processor refresh which would have offered even better all-around CPU and GPU performance.Today we'll be looking at our first notebook based on Intel's second generation Core processors, the ThinkPad X220.
