I'd say so yes. The GPU performance if the 4460 is used is not THAT far behind Exynos, I'd say around 6-8 FPS less in games. So, switching between/launching apps with the two should be no difference.
I use an iPhone 3GS now (hate this device), and I routinely have to wait up to 6 seconds to load my contact list. Its like running Windows XP on a 486.
Guys, wasn't there a comprehensive website that discussed all things nexus prime? It was loaded with factoids. I have been googling it, to no avail.
