As for me, I recently dusted off my Nostromo SpeedPad n50 and am enjoying good results. It's hard to change play methods after having been a mouse-clicker and keyboard tapper for so long. But, my old n50 is making Guild Wars even more of a blast.
I own the Nostromo SpeedPad n52 as well, but it had entirely too many keys for what I needed, so I reverted to the n50 which has a simpler design.

Now, I bought my Nostromo's several years back, but I know their are other gaming devices on the market. Zboard comes mind, I had used the WoW version in a previous MMORPG life, but unfortunately the cat spilled beer all over it. :/
So, let's talk "how" you play, things like:
Does anyone turn off the UI (shift+ctrl+H) and play free-style?
Is the keyboard only used when you need to type in chat?
Does your hand ever leave the keyboard?
Who knows, maybe some people may feel inspired to change their gaming methods like I did... after all, it's good to rewire your brain on occasion.
