I have a Windows Phone as well. Try Board Express, it's a Tapatalk client for Windows Phone. It's not ideal but it works well enough.
Aye, I was taking a look at it and saw the bad reports on it, might give the trial a go. Shame that WP doesn't seem it will ever get the kind of app support iOS or Android have, especially as Microsoft seem to have given up on it with the impending Windows 8 release.
I don't think so. I was with Android from the start, I had a G1 in November 2008, and it took a good year and a half for the ecosystem to become somewhat comparable with iOS (the launch of the original Droid helped). I'm hoping with the release of the Nokia 900 WP7 will get that similar push.
