How can you seriously multitask on a retina ipad with less than a gig of ram and no virtual memory ?

  By jailbreaking and installing "OS Experience" like the article says? The device was designed with to use a low amount of resources.

  With much greater ease than you could multitask on 8mb of RAM and a 32Mhz CPU: http://en.wikipedia.org/wiki/Macintosh_Centris_650 http://en.wikipedia.org/wiki/Macintosh_Centris_650

    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.

  So many downvotes, isuppose i'll have to explain myself : Apps for the ipad frequently run into memory warning exception, even when running on their own. One reason is the use of multiple layers of images to build a screen ( background, multiple panes on top, etc) which take a huge amount of memory even before you've loaded any data. Now, i suppose that the cydia hack didn't add a virtual memory manager to ios. It simply lets you see application in background. Now that means even more pressure on the memory, thus my question. Running twitter and mail isn't a problem of course, since they probably don't take half the ram. But "big" apps, like safari ? I doubt it.

    I guess the memory limit is per app by apple. To preserve the device battery maybe?
