palmtreerfb,
I've never used Ximarin before, but I do love C# and Mono. Is there a free/open/comunity version of the tools, or do you have to buy both the Android and iOS versions?
I built this little monitor toy in about an hour as a Flex mobile app (yeah, gross, I know..) so I'd have something to monitor with this weekend. Unless I can find an open source cross-platform toolkit this may be my first Android app that is more complex than "Hello World"
