So, here is my dilema...I am about to replace 4 year old MBP...want TB display with laptop to occassionally use around the house...so I am not sire if I should get 11 or 13? I mean, I love the idea of how small the 11 is and would look on the desk with the TB display...very sleek and taking up little room. I only occasionally would disconnect from TB display to use around house as laptop...so my thinking is why get the 13...seems both can be speced to be about the same power wise. Any thoughts...?? thanks
