Except most UIs on today's ipad use retina images. Meaning 1024x768x4x4 = 12 mo of ram for a single fullscreen image. Most applications run into memory warning

Except most UIs on today's ipad use retina images. Meaning 1024x768x4x4 = 12 mo of ram for a single fullscreen image. Most applications run into memory warning at some point even when running on its own. I can't imagine having 3 or 4 in parrallel without virtual memory.
