BlackBerry PlayBook vs. iPad vs. Galaxy Tab vs. Streak

BlackBerry PlayBook RIM Research in Motion finally announced its long-awaited BlackBerry tablet, the 7-inch PlayBook (thankfully not named the BlackPad). While there's still quite a few missing details, and nary an unit in site for us to try first-hand, we've still got a sampling of specs for this little guy to go t�te-�-t�te on the quantitative field of proverbial battle, at least as it can be seen so far (that early 2011 release date is still a ways off). Looks very promising so far, lined up against Apple's iPad, Samsung's Galaxy Tab, and the Dell Streak, but our known unknowns -- i.e. price, app support, and overall feel of using the QNX-built operating system
