Both of these are good, but I like S60 WRT when it comes to building widgets for S60 (Symbian) platform. If I have to build widgets for different mobile devices (running on different platforms), Yahoo! Mobile Widget (Blueprint) is good option.
I have to learn new things, which is good, but I was wondering – why can’t I use my existing skills (ActionScript + JS/HTML/CSS) to build things for mobile devices without learning new workflow and technology?
When are we going to see Adobe Integrated Runtime for mobile devices – Mobile AIR? Life would be lot easier, I could transform a lot of my ideas easily into applications?
Hope it happens soon, really soon.
