It has been discussed, but a little fresh perspective from time to time never killed anyone.
I upgraded from a 6700. The keys are a little smaller, but having more keys almost instantly sped up my thumb typing. Passwords are MUCH easier to type in for example. The Original GSM/Sprint layout so far is the best imo, as I use numbers far more than special characters (ATT Fuze swaps those for a more "traditional" T9 layout).

The keyboard material also feels grippier than my old 6700, but I never had a mogul so I can't compare that.

I would say the five row is the best mobile keyboard I've used yet, and that's counting BB's, Treos, and even the old thumbboard attachments for my old PDAs.
