iMac + MBA Combo or MBP? I know, another buying advice post... Currently have a mid-2011 MBA 240GB SSD, but I'm running out of HD space. I use it between work, home and school. Primarily it is used for writing, emails, photoshop, web and graphic design, and photography. We recently ditched cable and Netflix DVDs so it's also becoming more of a entertainment device. I have a 2TB Time Capsule and several other TB external drives; which is where all of my movies and some of my music is stored. I already have a 24" external monitor, Apple wireless keyboard, Magic Mouse and Touchpad that I use the MBA on in my home office. When I take it to my office for work, I usually just work on it by itself (I work more at home than at the office). Typically when I travel, I just take my iPad (unless I plan to do design work on the go). I know I could potentially just upgrade to 480GB SSD for $600, but with a 2011, I'd rather invest that $600 into a new computer with the space already. My question is should I get the new 21" iMac with fusion drive to combo with the MBA + iPad with the plan to get a rMBP in a few years? Or should I get a MBP (non-retina, I need the HD space) when they potentially refresh to Haswell here is a few weeks? I'm struggling to determine if it's a benefit to have the iMac to act as a desktop or the MBP as a desktop with an option to go mobile? posted this in both iMac & MBP forums to curtail bias.
