Aw crap.

If you’re a web designer, you really, really need to get a Retina Mac­Book Pro so you can see how bad your site looks on it and fix it.

If Marco says it’s true, then I guess it must be true. More of his rea­son­ing is fleshed out here but this quote sums it up pretty good:

Even though it’s (retina dis­play users) a small mar­ket today (although don’t for­get about the iPad 3), it’s inevitably going to increase sub­stan­tially in the near future. Don’t you want to get ahead of that? Do you want your site to be ready the first time some­one views it on a Retina screen, or are you OK with it look­ing like garbage for a few years until you hap­pen to buy high-​​DPI hardware?

I’m not actu­ally going to upgrade any time soon, but my next major com­puter pur­chase will def­i­nitely have some sort of retina/​high-​​DPI capability.
