There's no doubt about it - OS 5.0 (and the general BlackBerry "feel") is becoming a bit long in the tooth.  My guess is that RIM realizes this, as they seem to be a bit more proactive about OS 6.0 discussion (as long as I've covered them, they've often been tight-lipped about future plans) than they have been in the past.

RIM co-CEO Mike Lazaridis told WES 2010 attendees that OS 6.0 will offer better integration with touchscreen devices, but is intended to work with both touchscreen and trackpad-equipped devices.  Fluid transitions are expected to be included in the latest OS, and that Webkit browser that we're all anxiously waiting for is said to be included.  Lazaridis told the audience that the new OS would ship in the "next calendar quarter." 

Much more to come on OS 6.0 as the week progresses (hey, the convention hasn't even started yet), so be sure to stay tuned!
