A friend of mine has just purchased a very nice iMac as they are fed up of Windows. One of the programs they are reluctant to leave is MS Office accounts. Is there any preferably free way that this can be run within OS X? The owner is not very technical so the easier the better. They dont want to have ti dual boot. I have had a very quick look at virtual box but think this may be overkill and I'm not sure how easy that would be to setup?
