i have to carry another phone because the n900 doesnt last all day, i also prefer my iphone gps so i use it for that , and i also prfer the speediness of the emails on my iphone. not because it cant take phone calls or txts, because it isnt as good as my other one at the newer things we need on our phone. these devices allow me and many many others to save alot of money by not needing as much office staff, but they have to function well , or its all a waste of time.
