Native apps for Palm WebOS phones

Please consider making applications for the Palm WebOS phones instead of just web front end apps like Google does. Google maps for WebOS is very weak and I think Yahoo could easily out do Google in this market. In fact, a Yahoo map turn by turn application would own the WebOS market.

Palm's support for Yahoo mail is very useful but I would like to see a native Yahoo Mail application that includes Calendar and Contacts.

Microsoft has their new Windows 7 Phone, Google has Android and Apple has the iPhone. Why can't Yahoo have WebOS?
