RIM may use BlackBerry DevCon to unveil its repeatedly rumored BlackBerry-related tablet. A San Francisco event on Monday, before the conference in earnest, is said to be very secretive by ZDNet and might precede the actual keynotes for the event, which start with co-CEO Mike Lazaridis' presentation at Moscone Center West. While not necessarily a revelation by itself, it would come just as major companies like Citrix are reportedly promoting services and other products that would support a RIM tablet when ready.
