This years Toshibas Kirabooks are getting an upgrade, with a new Haswell processor, better battery life and a lower price. The new models of the ultrabook are rated for 9 hours of battery life and will retail for $100 less than previous models, slated to arrive in stores in mid-February for $1,499. The new Kirabooks will also feature Toshibas high resolution PixelPure display, in keeping with previous models. Toshiba has pitched the laptop as a flagship Windows competitor to the Macbook Pro and Chromebook Pixel, making the spec comparisons particularly crucial.
