HMM i used spb with winmo and well it was nice but it was a battery killer and it was laggy also it never really took over as the main UI it just ran on top like an app that never shut down. Now they may have changed this because android is a better OS than winmo will ever be and it allows full control to outside UI programs. and if this SPB taps into the what is a "sitting beast" of a graphics cpu on most android phones this will change everything because android up to this point has really done nothing to use the dedicated GPU on the higher end android phones.
