It seems like only yesterday we as web developers overcame the challenges of developing for multiple screen sizes that another challenge comes along: high resolution screens. No longer does 72ppi based graphics look sharp on the new hi-res Apple products because of the density change — the pixels per inch (ppi) have been doubled. While it’s a challenge to accommodate both desktop and mobile “retina” devices, I believe desktop will eventually go to hi-res as well.
You can see how we’re progressively viewing information. The printed document is becoming obsolete and the majority of information will be viewed on tablets, phones and desktop in the future. Everything will be on a screen. People will want the same feel of paper and the same sharpness of physical print. Print’s standard resolution is 300dpi (dots per inch). Maybe this number will be applied to screens too, perhaps 300ppi?
I don’t know the numbers, I just see it going here and while it’ll be a challenge to develop sites while desktop gets on board, I welcome it and understand why Apple came out with the retina display: because they are the leaders in this kind of stuff. Soon we’ll be encouraged to get a hi-res monitor to match our sharp mobile devices. This happened with DVD to BlueRay and with TV to HDTV. As tech continues to mimic real life, this is how things will go.
