Every MacBook I buy end up being the best one I’ve owned thus far. Considering this, I have absolute trust in Apple’s ability to iterate and relaunch its MacBook line at regular intervals. That said, following rumors about a retina MacBook Air, I can’t help but tell you what I think would be the perfect MacBook.

It’s really simple. I want a 12″ retina MacBook Air that can power a 27″ retina screen. That means decent GPU, adequate CPU and RAM starting at 8 GB. I’d also want, nay need, 512 GB or more SSD for all my music and photos and whatnot, preferably without paying with one of my kidneys. None of this is science fiction, this isn’t a dream setup or anything, it’s just what I want.

I hope Apple’ll replace both the 11″ (which is wide enough but the screen lack in physical height) and the 13″ Air with this 12″ device. Cut the bezel and you’ve got a machine that is essentially the size of the 11″ Air, just a wee bit taller, but closer to the 13″ when it comes to productivity.

The 13″ retina MacBook Pro is the best computer I’ve ever had, and I absolutely adore the screen. But I could make do with the same retina resolution on a 12″ screen, 13″ would do with a slight bump in optimal resolution if anything. 12″ just makes more sense.

That’s what I want, and that’s what I hope Apple’s got in store for me. That’s the computer I’d buy to replace my current one. At least for as long as I need a traditional laptop at all…
