Palm was very active at the Web 2.0 Expo and CTIA Wireless trade show this week, where we learned some more about the upcoming Palm Pre and webOS:

Palm Pre gained new applications;
a Palm OS emulator has been developed by a third party;
an early access program will open webOS to more developers;
cloud services from Palm have been announced.

To satisfy your curiosity, more material regarding the two events is available at The Official Palm Blog, where you will find a collection of links to videos, photos and articles.
