It's optional
Unlike Apple I don't see Google saying you have to use their system. Linking to a website to take customer's money is fine but if you want the simplicity of single sign on through the user's Google account then you pay 10%.

The new nano is actually slightly larger in volume - 1.4% - and heavier than the old nano - 23%. This is using the figures from the Apple website.
New: 69.8x52.3x6.5 mm = 23728.51 mm3, 49.2g
Old: 90x40x6.5 mm = 23400 mm3, 40g
The original poster is wrong is saying that it is thinner.
