The PlayBook is functionally incomplete, not fully or easily compatible with Android apps, and, more important completely and utterly doomed. This product is worthless at any price, and while I understand that some people won't be able to help themselves, if only to get a decent portable video player ... actually, that may be the only reasonable excuse to buy one. But beyond that, just say no.
The RIM PlayBook never had a chance, and nothing is ever going to change that. I'd examine existing Android tablets, which are available in a variety of sizes and price points, or Apple's more expensive but far more usable and viable iPad line. Or wait a few month for the iPad 3. Or wait 6 months for Windows 8.
Granted, the prices are excellent. At $299, the 64 GB version of the PlayBook, which will no doubt sell out first, is a whopping $400 off its original price. (The 32 GB version, also $299, is a $300 savings, while the 16 GB version, again at $299, is a $200 savings.) But remember the basic rule of shopping: It's not a "savings" if you don't need it.
And no one needs a RIM PlayBook. You deserve better than this. Wait.
Note: The RIM online store is apparently getting hammered, though it was working a few minutes ago. Why did you even visit that site? What is wrong with you? :)
