Can I buy an Apple TV remote separately?
The Apple TV remote is fairly small and could potentially find its way to an odd part of your house, not to be seen again for years, if at all. If this happens to you, or if you step on it and break it, you're in luck, because you can purchase an Apple TV remote separately from the Apple TV. You can find it at the Apple Store under Apple TV -> Accessories.
Alternatively, you can control your Apple TV from your iPhone or iPad with the Remote app, which is free and gives you a lot more control and is much quicker than the physical remote.
