The initial version of RIM's PlayBook tablet, which is slated for release before the end of March, will be Wi-Fi only, meaning it won't have any sort of cellular radio for wireless connectivity. This isn't exactly ideal, since the PlayBook won't be able to access cellular networks on its own. But the lack of a cellular radio could actually be a good thing for IT, since it means that no additional PlayBook data plan is required.

RIM has stated that PlayBooks with cellular radios will become available in the future, and said it would offer a 4G, WiMax version of the PlayBook this summer.

"It's a BlackBerry," Bidan says. "We're known for great battery life."
