So my mom wanted to buy a laptop for my sister so she ask me to choose a laptop for her. And since i knew that my sister does animations and drawings i had decided to choose a 2 in 1 laptop since its touch screen and it can turn into a tablet. I had choose 2 of these laptops, the lenovo yoga 500 15isk (i5 6200u) and the lenovo yoga 520 14isk (i3 7100u), its quite hard for me to choose since the yoga 500 has a bigger screen and it has a more powerful cpu than the 520, but the 520 is more newer and it has a m2 slot for me to both use m2 ssd and HDD while the 500 does not have a m2 slot, both are the same price, have fhd display, ram upgradable and does have a HDD slot. In terms of weight the 15 inch is heavier of course but i think she really dont care much about the laptops weight since she always stay at home and doesnt go out much. Which one should i choose?
