Can my laptop handle Starcraft 2?

Ive been really looking into getting starcraft 2 lately, I know, late on the whole starcraft train, but ive been watching a lot of MLG matches, and i want it. But i dont want to get it if my laptop cant handle it, or run it smoothly. I have an acer ASPIRE 5251-1513. It has an AMD processor V120 (2.2GHz) ATi Mobility Radeaon HD 4250 Graphics card. I upgraded it to 4GB of RAM. And thats all i really know about it from reading the sticker here on the side. Im not really sure of computer speak...so im sorry if i sound like an idiot. But i really want to get starcraft 2 (even though i dont have any money to get it... le sigh) but i dont want to get it if i'd be wasting my money. Can anyone help?
