I have been a proud Windows Mobile phone owner for a long time now and there is one thing I see that is more special about WM than other phone OS, a big community. Windows mobile has by far from what I see the largest community out there. If you need anything, windows mobile has it or you can find someone to make it for free or low cost. Xda-developers is one of the more larger communities, but it is centered on HTC devices.
There also smaller sites that are phone specific for an example Lg incite has Lg-incite.com and the Samsung omnia has samsung-omnia.org . There many more sites that are similar to those, and they are all there as a community to help anyone that has a problem. If you have a windows mobile that is not an HTC phone, or even if it is and you want to go to a more settled and a calmer place, I would give these siteâ€™s a try at least once.
