have you tried Windows Phone lately? I have an SGS3, an iPhone 4S, and a Blackberry Bold 9900, and yet my daily driver is a Lumia 920. Windows Phone 8 is surprisingly polished. And since the release of Instagraph, I’m not missing anything. Microsoft is putting out some quality stuff these days. You should try it.
I absolutely LOVE my Surface RT. But the critics are correct for slamming it for lack of apps. I was kinda hoping Microsoft would offer a 3rd Surface option with the updated Atom chip. Full Windows 8 and great battery life, best of both worlds.
