Facebook Home and HTC First

All of Facebook Home's innovations are good, in a vacuum. The gestures being used seem well considered and generally intuitive. But if you've ever tried navigating around an app—say, the Facebook app's sliding panels—on a phone that's more than a year or so old, you'll know where this can go wrong.

The S3 and One X are the oldest models running Home, and those should be more than capable for now. Facebook says it's adding "more devices in the coming months". That probably means just newer models that can handle the software load, but if Home does find its way to your old junker, be advised you might just end up with more Facebook than your phone can handle.
