If you want a longer battery life then you might also want to consider the B50-80[pl_3140584_price] (5.5h), the B50-80[pl_3812194_price] (6.2h), or the G50-80[pl_3258707_price] (7h) all from Lenovo which is also cheaper.

Portable PCs with a better storage medium that might be worth considering include the Asus UX301LA[plb_3012206_price] (SSD and higher rated); or the Lenovo X250[plb_2899793_price] (SSD and cheaper).
