I do not use acoustic room treatments for two reasons, money and space. As a college student, room treatment aren't exactly cheap, and truth be told, they are pretty much last on my lis of upgrades. Don't get me wrong, I want to purchase some later in life, but now is not the time. Second is space. Because I am living in a dorm (home at summer), there really isn't much space to put up any treatments. I would at least wait till I got an apartment so I had the room to do treatments (which if everything goes according to plan, should be within the next year or so).
