Doesn't it mean you now have two devices to carry around instead of one? I used to have one regular phone for calls, SMS, and one iPod for calendars, notes, etc

Doesn't it mean you now have two devices to carry around instead of one? I used to have one regular phone for calls, SMS, and one iPod for calendars, notes, etc. Now I have two in one in my smartphone which I find way more convenient. Charging's not an issue and if I want to stay focused I just turn it off.
