Chicagod,
As a Windows Mobile user myself, I understand your concern.
If you are using a WM device with a good resolution screen, you can bring up our UI on the device’s browser. To help with this, see our document at [url=http://www.CasaTunes.com/guides]http://www.CasaTunes.com/guides[/url] titled “Browser Customization” which shows you how to make the UI smaller.
At this time we are not planning on creating a custom UI for WM, but we will revisit this later this year. Also, perhaps some techy owners will consider using the development tools we have released to create an open source app for WM (hint hint). See the other posts in this Development section of the forum for more details.
Although it does not let you reach into your pocket to pull out your WM phone and change the CasaTunes settings, the iPod touch does make a nice, relatively inexpensive, remote control.
