HELP!!!!

I can't decide which phone to get.... T-Mobile Dash or the new T-Mobile Wing. Both phones have what I have been looking for (Windows MObile --- allowing be to edit Excel, for me to manage my account...). I am so torn!!!! T-Mobile Dash has faster CPU processing than the Wing... I like how the Wing looks like. The Wing is still new, so there's really no way for me to get a feedback. I only read reviews about it, and it was good. I also like how the Wing looks like, but I don't know how long will I stand having a bulky phone. Same goes with the Dash, yes it is slim, but it's wide! I like the touch screen feature of the Wing... I just don't know... help!! anyone??
