It's a funny thing about the $199 price point. When Amazon uses it, it's seen as a bold move by a confident organization poised to make a huge play in the tablet market. When Research In Motion does it with the PlayBook tablet, as it's doing on the day after Thanksgiving, it's hard to see it as anything but a desperate bid to stay alive. Only Staples has confirmed the price so far, a $300 drop from PlayBook's regular price, but others are expected to fall in line. So the big question: is this a sales promotion to get PlayBook into the hands of people sure to love it or is this a clever inventory dump? The tablet has been selling poorly and updates have been delayed.
