I'm pretty excited that we finally have some beautiful Apple hardware with Retina displays so the OS X HiDPI dream is actually turning into reality.
Needless to say I'll be updating Flying Meat's apps to take advantage of this.
VoodooPad 5 already has HiDPI graphics baked into it already- for instance, the toolbar is completely ready for Retina and it looks great. There's just a handful of other places that need to be cleaned up and it's good to go.
Acorn is being "Retinafied" (@2xed? HiDPied?) for version 3.3, and this involves a bit more work because I'm just not going to update the graphics for it (that's the easy part!). Oh no- there's something a bit more awesome that's being worked on:
What's a "Retina Canvas" you ask? Good question! A Retina Canvas is when 1 pixel equals 1 physical dot* on your hardware display, even though all the other UI elements in Acorn are redrawn @2x. Acorn 3.3 will detect and make the necessary adjustments for display and input** so that it looks freaken' awesome on your Retina MBP. And Acorn 3.3 already looking pretty rad.
So that's the plan, and I hope to have it done soon. If you've got a Retina display and would like a sneak peek- you can download a beta of Acorn 3.3 with Retina Canvas today.
