You say that consumers don't care about hardware and then in the same paragraph you suggest that the iPad 3's rumored hardware specs will trounce the competition. Believe me, when Apple releases the iPad 3 there will not be a channel on TV that will not broadcast its hardware features 24/7. I think people do care about the hardware if it means a substantially better experience such as a high resolution screen for book reading, a fast data connection like LTE etc etc. You may be right that people may not care to much about a processor--unless the tablet starts to lag.
Anyway, we'll see. I hope RIM gets it together and gets Android apps running on the Playbook--that will make things substantially better. However, by February there will be some compelling competition on the block so I hope RIM is testing the Playbook successor now. If not, I believe RIM will be exiting the tablet market, despite what it is saying now.
