I know this has been discussed before but I thought I would bring it up again.
StyleTap allows you to run Palm OS applications directly on your PPC. Now you can brag to all of your Palm friends about how you can run both WM Software and Palm Software. The cool thing is palm users still cant run WM software. You can check out the software
here. I know it costs money but it could be worth it to someone who has previously invested in Palm software then have moved to WM.
PS....If your nice about it, PM me and I might be able to get you a Registered Version.
