Apple is already killing off device support, sometimes (seemingly) for marketing reasons. With iOS 6, Apple dropped support for the first-generation iPad, but continued to support the iPhone 3GS (which I cannot imagine being much faster [edit: see Xuzz's reply to this comment]). The obvious reason, from my layman's perspective, is sales: the iPhone 3GS was on the market more recently, so the (newer) iPad got the ax.<p>Apple also tied app support for the iPhone 5, and future iPhones, to ending support for the iPhone 3G and its ilk; I understand that long build times are far from desirable, but this move seems like a great way to encourage upgrades.<p>Then again, maybe I'm just a cynic.<p>Edit: I've not used an iPhone 3GS on a day-to-day basis, but I've seen better performance out of my first gen iPad (and maybe it's just me) just before it was EOL'd than I ever saw with the iPhone 3G/iPod touch 2G family, both of which were truly awful performance-wise before Apple pulled the plug. I'm guessing the real reason for keeping support for the iPhone 3GS but not the iPad 1G was, as coob mentioned, the fact that it was on sale when iOS 6 was released.
