It looks as if my smartphone decision is being made for me, and I will need get an iPhone.

Firstly
1) I don't listen to music on my phone, prefer in the car on the PC or via the stereo
2) I prefer to use my own digital camera, Canon G7
3) I may have at most in the live of the phone only about 20-30 apps that I will constantly use

I will have one "company app"
I will use gmail and calendar
I will use ... other productivity related apps - tasks/todo, contacts, etc.

Would 16 GB be enough, or will I find I will hit the limit very quickly.
