As an aside: If Apple do transition to a flatter UI (yes, I know it's all rumor and speculation, but humor me), I'd expect to see a reasonable jump in UI responsiveness of older iOS devices. Not having to load many Retina-sized background images for UI elements would significantly decrease memory pressure on the OS as well as increase responsiveness. NB. Assuming older devices will be able to upgrade and that texture-heavy UI elements would be phased out. Edit: Typo

Same for CSS; I remember when I played around with CSS3[1] many moons ago, and it just slayed my laptop browser at the time. A lot of people like to use CSS3 for no reason, and it's actually a huge burden on some devices. And that's disregarding the backwards compatibility aspect altogether. Just as images and assets can be a pain for data plans and low bandwidth, "fanciness" can be a rendering bottleneck.

All depends on whether it's flat or "flat". Apple is the kind of company that would use a subtly textured background even for the flat UI.

Only iPhone 4S and iPhone 5 will be upgraded, right? Those have pretty good GPU's. It was iPhone 4 that had a pretty terrible one combined with the retina display at the time. The biggest impact would be seen on iPads, because iPad 3 actually took a step backwards in terms in performance behind iPad 2, when it switched to retina, and iPad 4 barely matches iPad 2 in performance (if we're comparing native iPad 2 apps vs native "retina" iPad 4 apps). It could also be the reason why the next iPad is rumored to not have a huge battery anymore, like iPad 3 and iPad 4, and be much slimmer (the last 2 iPads were thicker than iPad 2).

  I think the iPhone 4 will get the update, as it's still being sold. (If I had to guess, it's probably selling pretty darn well in the U.S. as it's Verizon's first "free" iPhone.)

    The 4 will definitely get the update. The 3GS may or may not, though it's already way outlived the support life of both the iPhone and the 3G.
