The unit made a good impression at first glance. Beautifully finished and chic. The device, however, is more apparent than real. Processor awful slow. The touchpad is on sprung sensors and is rickety. The mouse buttons are indeed today rationalized to light more and more. But Sony I would have expected better quality. The device was designed for my friend who look only times on the Internet servt and NEN film and wants to listen to music. But the processor is not acceptable. Screen and keyboard is good. Unit returned. Then we have the Toshiba Satellite C55-A 1PC and HP Pavilion 15-N020SG ordered. The new Satelite bad veratbeitet, sound cruel. >>>> HP has fully convinced. ... Good .. sound processor better than Toshiba ... unbelievable but true ...
