Following our press briefing with the PlayBook early today, we wanted to get a bit more up-close and personal with the BlackBerry Bridge software. Bridge, for those that don’t know, is the bit of technology that connects the BlackBerry handset to the PlayBook and allows for the use of BlackBerry Messenger, BlackBerry Email, and BlackBerry Calendar on the PlayBook itself. For the time being, Bridge will provide the PlayBook with all of its email, calendar, and BBM functionality — there are no stand-alone applications on the device. You read that correctly: without a BlackBerry on hand, you won’t be able to access any of your BlackBerry-specific messaging software. Don’t get us started. Regardless of this fact, RIM was kind enough to give us a demo of the Bridge connection and, for what it is, it works just as advertised. Any edits on the PlayBook are mirrored on your Berry, and vice versa. Drafts saved are accessible on both, and because all of the data is routed through the BlackBerry’s data connection, all Enterprise policies will remain secure and intact, which is definitely a concern for security minded companies looking to integrate tablets into their corporate environment. All told, Bridge does exactly what Bridge is supposed to do… the only question is whether you can live with having to tether your tablet every time you want to send a message.
