Unlike the HP deals, where you could get a cheap tablet and run Android on it, the playbook is dying on it's arse for two simple reasons.
1/ Buisnesses would never buy them as it's got "play" in it's title.
2/ Consumers would never buy one because it's a dead product with a locked bootloader.
Really, whatever idiot decided to call it the Playbook when their primary market was business, really needs to be flipping burgers right now, as I wouldn't trust him with much else.
They didn't help themselves either, with their mis-selling of their Android "compatibility", which got people's hopes up, only to be destroyed when the reality struck them that it wasn't runtime emulation of Android, it was compile-time...
