With WebOS just around the corner we know that HP/Palm is just building on what they have already started. I would hope that in the course of WebOS 2.XX that all the native apps get re-written in the native language, and that all things that can and should be GPU accelerated are.
But in later builds, I think it would be great for them to do something innovative with the home-screen. The current home-screen should be a long hold or double tap on the gesture area (I prefer double tap).
They could create multiple home-pages like android, create pages that are like scenes like the tiles in Windows Phone 7, or something totally unique.
The card metaphor is amazing for managing applications, but I personally do not my home-screen to be an application manager.
What do you guys think? How would you like WebOS to evolve from the current home-screen?
