Here's the differentiator: iPad, iPod touch *and* iPhone will be able to use iMessage. Also, you pay X amount extra per month for the BB data service, whereas iMessage will not require some ridiculous upsell just for their service.
You don't need a cellphone to use iMessage, either.
Nice one, Apple!![]()
You ALSO pay X amount of extra per month for Data service of your provider = iPhone or iPod Touch/iPad (WLAN at home you're paying for internet, just like the BlackBerry, while remotely for provider data you're paying for the data service - on blackberry its NOT an add-on its part of your data package).
where did you come up with that?
