My favorite commentary was ... because ... this calmly listed all the strengths and advantages of Nokia phone hardware and explained all the strengths and advantages of WP7 software (which I wasn't familiar with before).
# Windows Phone 7 is amazingly fast and responsive while also being unique
# Windows Phone 7 is rock solid stable and after using it since July 2010 I can confirm it is the MOST stable mobile operating system I have ever used
# Windows Phone 7 gaming rocks, Zune is fantastic, multiple Exchange support is solid, Office integration is great, and developers are building apps
# Email on Symbian blows, but on Windows Phone 7 it absolutely rocks and I prefer to use my WP7 smartphone for email handling over even my Outlook desktop client
