People who know a lot about computers or starcraft please help!!!?

Ok. So today i bought starcraft 1 to keep me entertained until sc2 came out in a few weeks. I went Home very happy with my new (lol) game and a reciept with a $10 deposit for sc2. When my dad got back i told him and he just went "grunt". Lol. So i was wondering what the system requirements were. Minimum system requirements were much better than what my winws xp laptop had. My laptop cost around $250>$300. Im not sure it was a christmas present. Anyway. I found out i couldnt play it and had a little fit. I need play it sooooo bad. My laptop nor my dads computer could run it because we havent got state of the art blizzard s*h*i*t. I dont see why they had to do such high standard sys req. I really want to play sc2 after seeing trailers and beta gameplays. Graphics are amazing and so is gameplay. I live in australia by the way. Can anybody recommend a chepish computer(preferably laptop) that could run sc2 smoothly? I mean anything that can run that can run anything right? But hen if i gt some super expensive laptop i will feel sort of guilty for having 2 laptops and only using 1. Please HELP!!!!
