One thing I noticed about the Fuze was that it does not have a dedicated number row of keys like Sprint's version does. Instead, its like the Mogul where you have to use the Fn key to enter numbers and the top row is instead dedicated to the special symbols/characters. Personally, I prefer the dedicated number row as I use numbers far more than symbols/special characters. Also noticed that the Fuze has an added PTT button (which cannot currently be remapped but I'm sure someone will post a registry hack for that soon enough).
