If you run it in a virtual machine it will be unusable with Garage band. Just go ahead and get the Macbook. If you wish to run Hackintosh on the laptop directly then let me know and I can code you some graphics drivers.
Haha, aight. So you say...no MacBook if I don't want GarageBand, but Sony Vaio? It all depends on which one I can upgrade more for cheap. RAM wise.
