Actually, Ubuntu Touch can "multi-task" just fine on 2GB of ram. Linux is nothing like Windows when it comes to memory usage. In fact, Windows Phone can "multi-task" just fine on 512MB of ram. Android is the only mobile OS that requires large pools of ram for "multi-tasking". Of course, proper "multi-tasking" doesn't occur on a mobile device anyway.
Btw...I remember multi-tasking on 8MB of ram.....and I run Ubuntu Touch on a Nexus 4.....
Okay then.. Chrome or FireFox Running.

It doesn't matter the OS 2 GB of RAM is weak for someone that really Multi Tasks unless your using really low usage Programs.
The purpose of blowing your screen up on a Monitor or TV is to do more than 2 tab Email/Facebook. I do use Ubuntu and Windows so I have a clue on how fast ram goes.
RAM Chips are stupidly cheap right now, the cost for a manufacture to go from 2gb to 4gb is less than $3 when your buying in bulk like they do, there is no reason why anything that costs $200 or more should have less than 4gb of RAM right now even if it is a overkill for most users.
