Jim Balsillie says BlackBerry PlayBook has a 'module cavity,' hints at NFC capabilities

He unfortunately didn't have one on hand (or at least on stage), but RIM co-CEO Jim Balsillie did make a bit of news about the BlackBerry PlayBook at the now-happening Web 2.0 Summit. The first is that the tablet packs what Balsillie described as a "module cavity" -- the most obvious use for which would be to add WWAN capabilities to the WiFi-only model (something Balsillie himself suggested), although the possibilities certainly extend far beyond that. Balsillie also later mused a bit about NFC capabilities, stating that "we'd be fools not to have it in the near-term, and we are not fools." That's obviously in relation to BlackBerry phones in general and not just the PlayBook, but it does seem like a prime candidate for that aforementioned "module cavity," which we really hope is not the final name.
