Guys, I gotta say... Unfortunately, the market is mainly iPhone (and soon to be Android) biased. Any place you go that is thinking of creating an app - iPhone will have it first (if not only). The apps made for the iPhone are just very well designed, they look great, and they're always coming out with apps for new and cool things. Windows Mobile is slow and not innovative (anymore).
Don't get me wrong. I'm a die-hard Winmo user, and will use any excuse to show our phones are better than iPhones (I tease my brother and friends saying they have a small screen and resolution - even though it's .1" smaller).
Also, there is an unfortunate problem with WinMo. It's too much work for the average user. Many people are just idiots, or lazy (no offense, but true). iPhone is an app phone. Not a modding mini computer (um.. Pocket PC??? Duh.). So for those people that really don't have the time or knowledge to spend searching for tweaks/hacks/regedits/roms/apps, they get an iPhone - and with good reason. It just works for them. No more, no less.
Like I say, everyone and their little sister has an iPhone. if you need it to do something, download an app. If you need WM to do something, you need a forum of seasoned experts. Sad, but true. And that's why I believe WinMo is struggling to climb to the top. It's not "easy" enough dor most people. For those capable of getting the most out of their phone, we meet here.

Luv ya guys!! Don't hate me for speaking the truth.
