The inPulse has been designed especially for BlackBerry by a company that makes dedicated 'Berry accessories. The screen is "big, bright and beautiful" thanks to OLED which also gives it good battery life. The thinking is that eventually the watch API's will become available to developers so that notifications from third party apps could be displayed on the watch. To drive home this major point, unlike LG's GD910, the watch does not replace your phone or make or take calls.It merely alerts you to messages or emails that have reached your BlackBerry handset. Within the business world there could be a use for something like this during meetings or other times when constant looking at your cellphone display would be considered bad form.
