Got my new rMBP today. Sadly being returned due to dead pixels but I get to keep it while Apple sends me a new one. I'm used to using my 2011 MBA on my lap. I find the MagSafe2 cable keeps falling out as my leg levers it up! It's driving me nuts! I much prefer the old style as it wouldn't easily come out with any upward/downward pressure... That being said, at least this doesn't block the USB port... Any tips for avoiding this, or will I have to stat using it on a tray!
