What is a hybrid?

There has been a lot of discussion and arguments around the viability and usefulness of hybrid devices (x86 convertibles). Personally, I think hybrids/convertibles are simply transitional - the future to me is cheap laptops or tablets running on ARM. But I'm putting it to you, the Tribe, to answer some questions about what you see as a hybrid and how it would benefit you in everyday life:

1. What is a hybrid?

2. Would you be able to use a hybrid as your only computer?

3. What specific programs do you see yourself using (x86 vs apps)

4. Any device(s) you are looking at in particular?

Bonus: Who would hybrids appeal to?
