I have a Galaxy S2 (4.3 Inch screen), which is about the same size as a Galaxy S3. I rarely make phonecalls with it.
I do lots of texting.
Browse with it.
It's an alarm, Calendar, handles email. I read some PDFs using it, although PDF reading is a bit of a trial with a small screen, but doable.
I use it as an MP3 player a LOT and even watch movies on it sometimes.
I even have a few games on it which I play sometimes.

So whilst it's a mobile phone, it's so much more then a phone and I don't really use it as a phone much.

When my contract expires I will be getting a galaxy note (5.5 inch), which is even bigger than the S2. At that point I will probably hardly ever be using my 9.7 inch tablet.
Most likely I'll be using the 9.7inch tablet for using at home and reading large PDFs.

A year ago I swore I would never use a Galaxy note as It was REALLY big to me, but I have changed my tune now, these smart phones are SO useful to have and even the larger galaxy note is small enough to fit in my pockets.
