Marco Arment makes a great argument for every web designer needing a retina MacBook Pro and I agree. The last design of this site I did was tailored first and foremost for the iPad. Now I am torn whether to tailor for the iPad or the retina MacBook Pro, because now I can’t decide which device I like reading on more.

>I think right now the perfect setup is a Retina MacBook Pro, and a non-retina external monitor.
Just be warned, you won’t use that second screen for anything other than testing.
