回复 我是bob啊 :cuz it takes more money to produce a 17.3 inches high definition screen..and it doesn't look too different between a 17.3 and a 15.6 to me since they're both pretty small anyway..if you want better experience watching movies,, a TV whose screen size is averagely over 40 inches is recommanded..on the market already are some very competitive laptops whose screen sizes are limited within 15.6 inches while equipped with a gtx980m graphics card or even gtx980 such as clevo p750dm(g)..after all if you feel like exercising every day then why is 17inches not an option..
