Just read this article on Steve Wozniak and his love for the Lumia 900. http://anewdomain.net/2012/04/26/apple-founder-inventor-steve-wozniak-why-i-love-my-windows-phone-7-5-fan/
I have had mine since the launch day and it has proven to be consistent, reliable and fast. The battery life is pretty great and i have all the apps i need. I am definitely happy with my purchase and i would recommend it to anyone looking for a replacement for a blackberry.
update, i guess this story is all over, another mention in eWeek http://www.eweek.com/c/a/Mobile-and-Wireless/Wozniak-Windows-7-Phone-More-Beautiful-than-iPhone-857635/
