Back to School Laptops

It's that time of year again, on for this year, my supplies list includes a laptop.

For the past few weeks, I've been browsing various laptops, and so far, I've come up with 3 laptops that may fit my needs.

The Asus A53SV-XN1

I guess the differences are the CPU (i5 2410 vs i72630, and the ram, 6 GB for i5 vs 4 GB for i7, and the HDD 5400 vs 7200). Anyone care to comment on these things?

I do not own or take credit for all of the above images and wideos, if you would like them to be taken down, please message me.

Which laptop out of the 3 would you choose? What laptop do you use? Any recommendations for any specific laptop or brand or specs?
