What is the best laptop/tablet to buy for post secondary schooling?

I'll give you a little background on what path I'm taking if that helps with what laptop / tablet is best for me. I'm going to college for a General Arts Program which includes history, English, health, philosophy, anthropology and computer studies. From there I'll be attending university for 4 years, the program i decide to go into depends on interests me most during my time in college. I'm also thinking about becoming a teacher so 2 years of teachers college. I'm not too big on computers so I honestly have no idea what's the best thing out there. I've been told Surface Pro 3 is the best thing. I was also told that buying a cheap laptop every couple years would be better. Any advice is much appreciated.

And, if not USA, you should have stated that.
Lenovo ThinkPad T440 14" HD Notebook Computer, Intel Core i3-4030U 1.9GHz, 4GB RAM, 500GB HDD, Windows 7 Pro (Free Upgrade to Win 10 Pro)
$440 plus tax in NY/NJ
Has a great keyboard, durable design, 4 pounds weight, a pair of batteries that one is user serviceable so can buy a spare for it, basic 14" display.
2705 cpu benchmark

fingerprint reader, trackpoint and touchpad, good Wi-Fi, bluetooth. 500gb 7200 rpm hdd.
upgrading:

It is basically a premium version of an industry generic 15.6 inch $330 one

with a 1TB 5400 rpm.

Surface pro is very lightweight, but costs much more, has a keyboard that is not nearly as good, and compare other features yourself.

I'm not saying to buy the Thinkpad, but a business quality laptop at a reasonable price is a good option to compare others to.
