Poll: What type of smartphone and/or tablet do you use?

My objective for this poll is to figure out three metrics:

1. How many people here use each of the three main mobile OSes on their smartphones;

2. How many people here actively use tablets;

3. How many tablet users prefer each of the three main OSes.

If you have more than one device in the same category (say you have both an iPad and a Nexus 7) pick the one you use/love the most in your spare time.
