in india 2nd gen pdc are 5000 cheaper than 3rd gen ci3. For studying, movieing and net surfing is i3 has any advantage?
For studying, watching movies and net surfing i would suggest a Tablet instead of a laptop. It's battery lasts way longer, its easier to carry around, and you dont need to boot/shutdown everytime, it's always on standby, and best of all, it's much cheaper than a laptop.
Unless you want to use your laptop for programming or design, i would recommend a tablet instead of a laptop.
