Hi guys, I'm running out of space on my 128GB SSD, and was thinking about upgrading to 256 rather than buying a new machine (though I love the 11inchers on the market). I am willing to pay 200-300 to have Apple do it -- is this an option? Has anyone used AppleCare/theStore to give your computer in for an upgrade? Does anyone know the price? And if this isn't an option, has anyone done the upgrade to 256SSD themselves? Is it hard to do? I'm sorta experienced with upgrading RAM in the older MacBooks... the iFixit guide seems to suggest it isn't too hard if you have about 15 minutes. Thoughts? Thanks.
