This kind of reminds me of the family I worked for as a nanny when I was 19. They lived in a Middle Eastern country and were rich on oil money and showed it in a rather gaudy fashion. They had bought an enormous property in the middle of slum (because they wanted river view), erected 5 meter high walls around it, built a huge palace with golden stairs and marble floors and door frames (I kid you not) and furnished it with crap imported from Sotheby's. At some point I saw a Sotheby's catalogue lying in the hallway, flipped through it and saw all sorts of vases, harps and statues from like 20,000 £ a piece, many ticked with pen. Then I could look around the hallway and find most of these things all over the place. The kids had a whole wing of the palace for themselves and flat screen TVs even in every toilet.
Anyway, long story short, they had a cupboard that was filled to the brim with all sorts of Apple Gadgets and Blackberrys. MacBook Pros, iPads and iPhones. I'm sure there were at least 10 of each, unopened in original packaging. I asked "why?". I mean it's fair game to throw out your money as you please, but considering that tech gets old and outdated so quickly, what was the point of wasting money like this? The mum proudly told me that they did that to
save money. Since they are weekly jetting to London (in first class!) it's cheaper for them to buy just-in-case-backup-units there, than - God forbid - buy at an Apple reseller in the Middle East in the rare case of an actually dead machine or even get their current machines simply repaired if something goes wrong. Yeah. Right. So financially savvy!

In reality it was just the 4-7 year old kids that kept breaking their iPads on a biweekly basis and fetching new units from the cupboard, the other gadgets were just dusting away into obsolescence.
Anyway, sorry for the long story, but this thread kind of reminded me of that.
PS: OP, just get an external drive and put Mavericks on there.
