RIM has stopped making the 16GB Playbook. Engadget has the story and this comment from RIM’s PR:
RIM will no longer be making the 16 GB model of the BlackBerry PlayBook tablet. The 16 GB PlayBook will continue to be available for distributors and retailers while quantities last. We continue to remain committed to the tablet space and the 32 GB and 64 GB models of the BlackBerry PlayBook continue to be available from our distributors and retailers around the world.
There is more value for our customers in the higher capacity models (32 GB, 64 GB), and as such we have decided to focus our efforts here.
Translation: The 16GB model is the first one we’ve run out of from our huge money-losing stockpile of inventory.
The PlayBook hardware is 14 months old. There’s only two options here: They plan to come out with a new PlayBook, or they’ll abandon the tablet business once the remaining inventory of 32GB and 64GB models are sold.
