>> The initial release was pretty bad, but subsequent ones are fine. Well, it seems there is some variability on this, so the better response may be "YMMV". iOS7 on my iPhone 4 (including the latest updates) -- just made it unusable -- and keep in mind, most of what I do are just the core apps, Safari, RSS and Read Later. I basically had the same issues with the last supported iOS versions on the original iPad and iPhone 3G. The pattern I notice is that Apple tends to offer one OS upgrade too many on older devices, which is basically what led me to leave iOS. The refreshing pattern I've experienced on Android is that most of the upgrades have featured performance improvements.
