Does not run under WebOS 2.anything. MotionApps sold it to HP <http://www.motionapps.com/classic/> and HP has stopped supporting it, so folks running WebOS 1.anything better get ready for it to die.
What's most annoying is that MetrO <http://metro.nanika.net/> will only run under ClassicApps on Palm devices. MetrO is possibly the most useful app for scheduling train trips in Europe I have ever seen. Glad I can run it on my netbook, though the phone'd be handier.
