I am buying a retina mac, and I am looking for a fitting sleeve for it. I have a 13 inch neoprene slim sleeve from Incase for my current MBP, and i really like these sleeves in terms of quality and plain design. However, I'm unsure if the 15 inch variants will fit a retina mac perfectly? They are listed under "15-inch MBP with Retina Display" on apple store, but they are tailored to fit a regular 15-inch MBP. As you all know the retina mac is considerably thinner, and i don't want the sleeve to be 'sloppy'. Does anyone have experiences with the retina mac's and (fitting) sleeves? Thanks!
