Although, undauntedly, all ThinkPad notebooks are quality products, sale rate is not something that Lenovo can be satisfied with, when it comes to ThinkPad notebooks. High price tag is, obviously, insurmountable obstacle for many buyers, so in Lenovo decided to offer models that will have basic and recognizable features of all ThinkPad notebooks with few compromises and significantly lower price. As result new ThinkPad SL series is created with models: SL300 (13.3inch), SL400 (14.1inch) and SL500 (15.4inch). We have got smallest model in our test lab: Lenovo ThinkPad SL300.
