I'am a big fan of WP since release of WP7, but I'am thinking that microsoft should close the development of WP as it is too late to fight against ios and android. But as a user of WP8 (lumia 920) i can only say that it's a wonderful product with genius ux design and super-duper hardware, that doens't freeze... practically never. I restart it every month in case the battery drains to 0%. Hope that it can make it in the future, but doens't seems to. About WP8.1 i'am so excited, and in few months hope to get the update!!!!
