I can’t even believe this is right.  For the Playbook’s email and calendar to work you need to be connected to a Blackberry?!

The question is: Who, besides BlackBerry users, is going to want to buy it? The core email and calendar apps are completely tethered to a BlackBerry. Without your BlackBerry, there is no native email or calendar app—just access through the (admittedly good) web browser.

That reminds me of the Palm Foleo strategy.  Never heard of it?  Yep, that good.

There isn’t a survey out there that has the BlackBerry gaining market share, so why tie (anchor?) your new product, which has plenty of positive attributes, to a sinking ship?  You immediately cut out 75% of your market (and growing).  Delusional.
