Nexus 10 Disappointing

I'm on the edge. Nexus 4 or Lumia 920? I'm not sure. There are a lot of positives and negatives for both and I really don't know which I want to go with.

But the Surface vs Nexus 10? It's not even a question, Surface all the way. I've seen Jelly Bean on a tablet and frankly I'm not not interested, specifically because it doesn't bring anything interesting to the table but more importantly there's a distinct lack of tablet optimized apps.

Can anyone show me how many tablet apps there are? Is there any definitive research on the subject? Because I would rather have 10,000 tablet (and rising) apps than 700,000 non tablet apps. I know Google doesn't let anyone know this number but can anyone say its even over 1000?
