There isn't much out there at the moment. With poor support for USB drivers I don't think there will be many plug-in accessories available this year.
We already have device-specific forums anyway, do we really need separate forums to discuss 12.1" sleeves and bags?
I can only spot one suitable bag for the S5 on Amazon UK!
We have a small site at the moment, and a smaller number of active forums with interesting daily topics is better than a wasteland of forums with a handful of topics each. A Lotus forum that I'm involved with (seloc.org) held off creating a dedicated forum for engine conversions until around 40 users were regularly posting topics on that subject in the general chat area.
