The Toshiba Satellite C50-B-154 notebook PC 15.6 "with a good design, the keyboard is functional, integrated high-quality webcam like the microphone, the terra byte (approximately 915Giga effective) is enough to store many documents , photos and more. However he sometimes still quite often "rowing", I mean the rapidity that its runtime is sometimes understaffed regime which is quite a shame for such a recent model, more about web browsing it is the same history, after about 3 hours I have to restart it if I want to watch something streamed loading becomes VERY slow, ditto when I open new tab. Regarding the apps menu windows 8 I delete most, these latter being mostly gadgets that I find useless. Apart from this large black dot that is the general slowdown device I'm still happy.
