Seems like you basically took the easy way out. Why not give each device its own subforum. Anything else is just darn confusing and makes us read through a large list of threads for which we have no interest. If I want to locate pertinent threads on my PRS-600, I don't want to read a huge list containing thread topics for several devices, especially since a lot of folks won't mention the device name in the thread title. I see lots of wasted time and frustration on my part.

EDIT: Ok I stand corrected as you have included a drop list to indicate to which specific device the posting is related. Much better. It will still be a crowded forum as far as threads go.
