I hear you all about keyboard width too - My Steel Series Merc Stealth tucks away under the 32" screen for Elite, I have a cheapo (£20) 'Cerulian' mini-board which I bought for the lappy but sits very nicely between the X-52Pro controls & still leaves room for an ashtray. VERY important!
I do have a Razor Nostromo, but am yet to find any real use for it in space - even if having it sat there makes it look much more like the cockpit layout.
I don't use my Logitech headset much in-game, mostly coz I have to turn the game volume down so much to use it without bleedthrough. Having no family & few neighbours means I can use my 550w 5.1 system the way the manufacturers intended

I did give headtracking a whirl, using OpenTrack & FreePIE - it works fine, but it just feels 'wrong' to have a moby on my head so I stopped.
