I personally feel like these are both excellent platforms with different strengths of course. I feel that BlackBerry OS is by far the strongest messaging platform out there, however the entire UI is dated and needs to be revamped. WM seems to be perfect for a person in an Exchange environment, and is highly customizable for those who like to tweak things... I also feel that it is way outdated and desperately in need of WM7 to be a real update, or 6.5.x for that matter. The level of customization of comps like HTC helps mask that need and bring WM to the current day though, and that's a plus in my book despite the whole "lipstick on a pig" part of it. I'm just looking for an awesome touchscreen phone, and the HD2 is in the running for me. If the Storm 2 was on another network, I might look at it a little more closely, as it seems to be pretty solid.
