I like as many controls as possible myself, and don't really like touch devices, to be honest, so I can feel wanting a dpad, but why specifically does the community need one on this mythical "N800 refresh"? I had the N97, and rarely used the Dpad or keypad, so I don't see what the deal is.
There are numerous valid reasons. Mine had to do with touchscreen wear. I'd rather relieve the touchscreen of heavy usage that D-pads endure (such as intense gaming).
New blood is good blood. If even 5% of new users decide to sign up here and decide to give back to the community in one form or another, be it through programming, support, bug fixes, whatever... the community will be in great shape.
