I really don't understand Nokia's interest in pursuing a scripting layer like this when they already have a stable full of developers and budding developers willing to make apps (which will be more efficient) with the system languages. A javascript app layer doesn't appeal to iJoes, so this move is puzzling. It's not going to get them greater market penetration, and will also turn off some of the more staunch supporters that aren't the kind that want to play with Barbie's Espoo Adventure. Those developers are already off playing with the borg queen and the Apple.
