Being a new mac convert since getting my mba last November I will obviously be buying Lion when it comes out. I am thinking of also putting Lion on a pc running windows 7 at the moment. Being a novice I wondered if someone would tell me if this a good idea, and also the best and most efficient way to do this. I have windows 7 on virtual box on my mba but rarely use it. Is it the same running virtual box on a pc. Thanks.
