Hi gyus, I would like to ask if anybody knows what's the difference in the macbook pro retina 13,3 models with the following codes: ME662 and MD213. Is it only the realease date? As I assume the MD213 is the first one that was released in late 2012 but it had 128GB HDD. Now they changed the HDD to 256. And the ME662 is the latest 2013 release. So eventually MD213 is the older upgraded and the ME662 is the newer that comes already with 256 HDD. Have I answered my own question , or there is more to it than simply release dates? Thank you in advance!
