See if you like it: Finch
Well, I have an installer ready for the 0.9 beta version of Finch PocketBlogger (see screenshots and walkthrough). I actually went a lot smoother than I had imagined, as I have virtually no experience in developing desktop (or palmtop) apps. I've been doing Web apps for 8 years now and I know my way around in VS.NET, but I had expected more difficulties on the way. It was definitely a nice experience to target the Pocket PC platform.
Feel free to download and install. It is free (although I would ask you to check out the About screen). Also feel free to send me feedback, but I will feel free to ignore your wishes. ;)
I will probably opensource this toy soon, but I'm not sure when and how.
Oh yeah, I almost forgot: Finch is built upon the .NET Compact Framework, so you need either Pocket PC 2003 or you must have the Compact Framework installed. The installer will not do this for you.
