MacBook Air 2013 or 2014?

Hey guys,

I'm in my first year of university and I'm looking to buy a new laptop. I've only previously used Windows and now I'm eager to jump on the OS X bandwagon, after hearing glowing comments from friends and also the almighty Internet.

Questions is, which? I know that the 2014 model has an incremental bump in processor speeds, but would the jump from 1.3Ghz to 1.4Ghz make a difference? For this processor jump, I'm paying an extra RM200 (I live in Malaysia) for it.

So does anyone of you guys see the difference and the need to pay extra?
