Photoshop is one of those things that easily illustrates how far computers have come. Anyone who used graphic design software, even well into the PowerPC days, remembers having a tiny preview window to show filters/effects, and then waiting seconds or even minutes for the filter to be applied to the entire image. Yes people, even a blur took a long time in the old days. The real-time manipulation we have on our phones these days is insane by comparison.
