Unless someone already replied, it may require more useful close botton (or toolbar) hovering above every app... such key combinations are too difficult for average users

I decided to join the community when I saw this thread. I am a flash developer and I love to make games. I have C++ and Java experience too (between 1990-2004). Currently I am building flash games portal for my own games (and other quality games). I had plans to make them work in N900 through web browser, but this may change all that.

Great job, looks VERY promising.
