Galaxy Nexus bought: Android n00b.

Hello

I have recently bought a Galaxy Nexus. I have been an iPhone user for the past 3 months and thought I would experiment before considering the iPhone 5.

I have the least experience with Android and was wondering a couple recommendations.

Whats the best apps out there?

And how could I sync my iTunes Library to the device.

Also some Tips & Ticks would be handy.

Cheers in advance,
