I've had my Windows 7 Phone for 6 months now. I love the interface and the Office integration that is there. Yes, things could always be better from any integration perspective, but the integration that is there, is wonderful. Technology is going to always be changing, and to developers on every platform I say, enough Calculator apps... That's great that iPhone and Android platform have 100's of thousands of apps, but how many do we really need? As someone who has had iPhone's and Android units, I'm sold on this platform. I look forward to seeing it get better over time!
