At first, I wanted to say 5 (windows phone), because that's just plain silly, and I think highly of you. But 9 (job at nokia) through me in for a loop, and now I'm not so sure anymore.
Also, 10 (ipad) while it seems like a silly prediction in retrospect, being contrary seems like something you would do.
Hmmm, I'd still go with 5 anyway. Let's see the other comments.
And thanks for the mention, this will be fun to craft.
