Apple has said that some features of iOS 6 may not work on some devices, but hasn't given any specific information about what features or devices that may be. This article will be updated when that information becomes available.
Devices not on this list can't use iOS 6, though many of them can use iOS 5, which still is a very good OS (find out what devices run iOS 5 here). That said, some of these models are three years/generations old, or will be replaced by new models sometime in 2012. If you're using one of these older models, maybe it's time for an upgrade anyway. IOS 6 and its great features makes a compelling case that it's time for a new device.
