I have it on my iPad, which I don't really rely on. It's sluggish at times and gets stuck sometimes (it seems, for instance, that a Safari View Controller won't init until you leave the app and then go back), but generally fine — except when it's not: it sometimes hangs altogether, eventually reboots automatically, and then gets stuck in a reboot loop where you'll briefly be able to unlock, then not be able to do anything, and then another reboot follows.

So, in short, no, don't install this unless you're feeling lucky and/or want to adapt your app to use new APIs.
