The fact is that the PlayBook is far too limited, especially in applications, to be any good to the average consumer, who would be better off buying an iPad or Android tablet. (Pay your money, take your choice.)
It has virtually no apps, barely any functionality (you can only do email and calendaring if you already have a BlackBerry, or if you're prepared to use a web-based system which might or might not work), and a small screen. What it's perhaps useful for is doing presentations onto HDMI screens via its HDMI output, because it can drive that while viewing something different on its own screen. Standard enterprise stuff.
But of course, you could take the view of Currys, which says that it is "slick, stylish and luxurious" and that it is "reported to be the 'fastest tablet ever'". (Nice use of the arm's length there.)
