Mogul??? Really? Great phone in its' day, but a little dated now. Can't compare curve and the others....totally different animals. Personally not a BB fan, but we do use the Curves at our place. Nice phones, great for what they are intended e.g. phone and e-mail primarily...little or no customization. Therefore looks like I'd have to choose a Touch if were in your shoes. However, I could never go back to a keyboardless device, so maybe it would be the mogul
