Alright I know this topic has probably been posted before, in fact I know it has as the last post I saw was from 2009, but with that being said a lot has changed since then so which application would you recommend. Keep in mind I'm entering college so right now Virtual Box looks quite appealing as it is cheapest (free). Last week I ordered a new MBP with 16gbs of ram so the allocation of memory to the VM shouldn't be of any concern. Thanks.
