Bumping, I'd like to put my input as well.
Lately i have become a bit more dependent on my phone, but this is mainly because of my time on here. If I didn't count that, then I would say I rank as a 4-5 normally, but I've chosen 5 because of the recent times. I usually use my phone to organize lists (this is only in rare cases when I DO need it, since I usually have an excellent memory), and do the usual call/text people, along with the occasional gaming apps, but otherwise I have no real need to use it too much since I don't like answering calls, though I don't mind texting.
Outside of my house, I depend on my phone a little more because wherever I go driving, I usually can't find a decent spot around with internet to use my laptop on, so most of the things I do on my computer my phone ends up taking the role instead. Outside I like using my phone as an mp3 player, browse the internet, and watch videos, which is pretty much all I end up doing with my phone as everything above becomes irrelevant to what I'm doing with my phone while out. It's not a bad thing to use a phone, but with all the newer technology that comes out, it kind of lessens the need for a phone at all when you can make text messages or FaceTime calls from something like an iPad.
