Blackberry PlayBook Rumored Pricing

Mobility Insider is reporting that they have the yet-to-be-announced pricing for the RIM Blackberry PlayBook.  According to their insider, the PlayBook will be priced according to the memory storage.  The rumored pricing will be:

• 8GB: $399
• 16GB: $499
• 32GB: $599

There will be no other differences among the three versions.  All three will be Wi-Fi only with a wireless carrier connectivity to be launched in 2012.  The pricing is competitive (at least the $399 model) with the $499 on par with Apple's iPad.  With a $100 difference for going from 8GB to 16GB, it is less expensive to buy a memory card.  Would you get the cheaper version and just buy a memory card?
