I’m absolutely loving using OmniGraffle on the new iPad. With the Retina display, diagrams are just incredibly crisp and sharp. Imported images from templates show up with a level of detail that is just astounding.
I am running across two issues that are admittedly, first world computer geek problems. The first is that getting perfect alignment in a complex diagram can now in fact be harder than on a lower resolution display. Previously, if a line between two objects was not perfectly aligned on a 90° angle, it was immediately visible as the antialiasing of the line jumped out immediately. On the Retina display this is not the case. The detail is so fine that slight misalignments have no visual cue as it’s perfectly capable of rendering them below the visual threshold.
Omnigraffle does a really good job with it’s auto-alignment tools so this isn’t a huge issue, but sometimes it will prefer to snap to edges rather than the middle so the connectors lines won’t be square.
Which brings me to the second issue. After working on a diagram on the Retina display that looks beautiful, transferring it to anything else is a horrible disappointment. The slight misalignments are immediately discerned, detailed icons look fuzzy and washed out.
I can’t wait until everyone else catches up with high resolution displays.
