Research in Motion continues to make a push from the enterprise to consumer markets. In what’s likely not a coincidence, the same day that RIM announces their new BlackBerry Bold, they also have a Microsoft deal to shout about. RIM and Microsoft have partnered to bring Windows Live services to the BlackBerry line: Windows Live Messenger and better integration of Windows Live Hotmail hit the handhelds by summer. Hotmail users will leverage the BlackBerry network’s “push” technology for real-time mail and they’ll also have the option of a separate or integrated Inbox for Hotmail. I prefer having one single Inbox to manage, but that’s just me; it’s nice to see that BlackBerry owners using Hotmail will get an option.
