Seriously? Your plan to fight iPhones and Droid devices is to tout your phone's multitasking ability?
How many consumers complain about their phone's multitasking capabilities? How many consumers even understand what that means?
[edit: If they are talking about the business meaning of "multitask", as some child comments have noted, then I agree that this would be a cool feature. I also find it annoying how hard it is to do work in multiple apps at once.]
