Does anyone here use a Window phone? I need to get a new phone and I was looking at the Samsung Galaxy Ace (Android) and the Blackberry Curve 9320, but the Nokia Lumia 610 is available for around the same price from Carphone Warehouse on pay as you go upgrade. It appears to be a more up to date phone but I'm unsure about Windows phone (it uses Windows Phone 7.5 Tango).
