Hello all. I'm new but I'm Apple fan for a long time. The reason why I'm posting in here is because I'm somewhat hesitant if it's right time to whether to buy both iMac 27" and Mac Book Pro 13" with Retina display. Should I wait until this summer or fall if there's any plan to upgrade both lines this year? Already have older Mac Book Pro from 2008 and late 2013 iMac 27". I have the cash to buy both and plan to customize the Mac Book Pro a bit like having 16 GB of RAM and 1 TB hard drive. Thanks for your advice in advance.
