News this morning on ZDNet about Microsoft moving away from Silverlight towards using HTML5 is more good news. I expect (hope!) to see more iPhone and Android development to be based on HTML5 rather than native apps.
As we see improvements in device independence (i.e., getting to read email, tweet, watch video, video teleconference, etc. on our smart phones, netbooks, laptops, Google TV, Wii, XBox, etc.) I hope to see real improvements in development platforms for universal applications.
