People keep complaining, and some Fanbois keep stating that Microsoft have taken the right decision long term, but they have been unable to commit to anything on the desktop for the last decade, and the phone is also following suit.
I lost my faith in Microsoft a little while back, and anticipated that Windows Phone would be chopped and changed like they have done so well before.
Apple have gone from iOS 1 to iOS 5, and I am awaiting Android 4.0 Ice Cream Sandwich to upgrade my 2.3 version.
Only a fool would buy a Lumia 900 phone now. If you have one, take it back.
