So I think a hi-definition "retina" level display would be game changing. It would improve the user experience dramatically. It is worth spending serious money on and also putting oneself in position to take advantage of it when it becomes available. My question to the group is do you think this is doable with current or nearly available technology? I'm probably going to buy an iMac on the refresh. I don't expect retina in an iMac this year. Could an iMac power a retina display in the near future (like two years from now)? Can current Mac Pro's power a retina display if Apple could build one? Are there any super hi-DPI displays on the market now? Can we expect some by the end of the year? I'd consider dropping big money on a Mac Pro this summer if I thought in a year I could attach a retina display to it. Does that seem feasible? Or are retina level displays years away? Note, I want at least a 21" and would prefer a larger display. If I were to buy an iMac now, I'd buy the 27". So 17" hi DPI displays aren't what I'm talking about. I need the number to start with a 2 or else it is too small for me.
