Tough Call.
I got one of those small laptops with 2Gbyte and 32Gbyte of Flash storage. It is slow but tends to go decently long on a battery. It is good enough for using office [or an alternative like LibreOffice] and small tasks. You can run youtube videos on it even... if you don't mind a bit of slow down.
But 2Gbyte, kinda puts it in that mark of, slow.
Its functional but slow. And yes for college, just taking it with you to classes? Nothing wrong with that. It probably is very small and light. For heavier work, oh ..oh no! They are not made for that.
I use mine to use LibreOffice and write documents. Thats about it.
Now if I would open 20 tabs in firefox and watch a few youtube videos. Well things will slow down considerable. So though it is enough for working on it probably it so slow for enjoyable usage.
Still why buy a 2Gbyte laptop? Because they are cheap. Because they are light. Because they offer basic functionality against a decent price. Because if all you need to do is office, take notes and need a half decent battery life guess what. These babies will do the job.
If you need entertainment a 4Gbyte laptop with a more powerful GPU/CPU will work out better. But those are heavier and tend to have worse battery life. Choices Choices.
