I have an iphone. I use it for so many things such as; a telephone, texts to and from the kids (I have an app where you can talk the texts and it transcribes it for me- I'm a messy typer), emails, facebook, a clock (cause I can't wear a watch) and I do use my camera a lot. I have several different types of cameras - for night or zoom features yadda yadda.
I also frequently use the flashlight, maps, calendar, yellow pages, google and the calculator. When I travel I use the translator a ton!
I frequently mix languages and this keeps the locals and I on the same page.
I write my self a lot of notes too, so it helps to have all the info in one place.
My favourite app is Shazam - you hold it up to the radio and it tells you the name of the song. My husband and I own a dj company - it helps me keep current. I have CBC and CKUA and WunderRadio, my fav radio channels on it as well. I also have meditation (stop smoking etc) on it the iPod portion. That ain't working so well...
"Bump it" is cool too. I can bump the phone with someone elses phone and transfer info - photos, apps, documents and the like.
I use several others too, but I don't want to bore you.
No games though... can't be bothered.
I never thought I'd be this dependent on the damn thing, but I'm hooked.
