Deciding on my next phone

Hi all,

I'm currently using an iPhone 4S, it's nice, syncs with my iMac, MacBook Pro, iCloud, iTunes Match etc it's wonderful. However as many, many others have pointed out, iOS is getting long in the tooth, Apple are failing to innovate on iOS IMHO. Sure they do some things exceedingly well, but they're not taking the needed steps on building on the good foundation they already have.

Before my iPhone I had an Android device, the HTC Desire — which burnt my hand after getting so hot. Android was horrendous back then. Buggy, slow as hell, no battery life and the UI wasn't very intuitive.

So... WP8? Is it a good'n? Is it worth switching to my Apple-full life?
