I went from Android to WP8. I agree it is fast. But its also very lacking in functionality, useability and apps. The only outstanding feature is the Skydrive and Office Apps. My suggestion – unless you really want the office apps, don’t even consider WP8.
And never pay full price like I did for a WP8 phone, they halve in value in about 5 months.
I love it when people present gross generalisations unsupported by data. The problem is most people will believe this sort of thing. (referring to the original post)
