The real revelation to me is how much of a different four years makes in computing power. While my 2010 laptop is still quite functional, technical advancements in CPUs, graphics chips, storage, batteries, hardware design, and displays have rendered it something of a dinosaur.
The only advantage that older machine offers over my new one is its larger display — and if I'd been willing to spend more money and carry more weight, I could have had that as well, via the 15-inch Retina MacBook Pro.
For my needs, though, the 13-inch Retina MacBook Pro appears to be the ideal do-it-all laptop. So, anyone out there need a dinosaur?
