iPhone 5 User buying a Lumia 920 to toy around with.

So I'm a tech nerd. Ever since Windows Phone debuted, I've always wanted to give it a shot. I've used android for a couple years, and I've owned an iPhone 4 and currently own an iPhone 5. I'm shopping on Craigslist and I'm going to pick up a Lumia 920. I don't use my phone much for multimedia. I mostly use it for social purposes like SMS, E-Mail, Facebook, Instagram and Twitter. I sometimes like to pull up YouTube videos on the go and I use my phone as my music/podcast device on my commute. What are the main benefits that WP8 has over iOS for my sorts of daily use? Is the social hub really a big help to see feeds all in the People app? Are there any daily functions that I would either find clearly improved or damaged from the move from iOS to WP8?
