The first reviews are coming in for the long-awaited Blackberry PlayBook, RIM's new tablet. Now granted, the iPad is a tough act to follow (unless perhaps you're the iPad 2), and most of the recent tablet entries have failed to win over fans, critics, or customers. Based on some of the early reviews, the PlayBook faces a similar uphill battle.

Many of the reviews published over the last few days have focused on the same issues: solid hardware, but not enough apps. Of particular concern - or bafflement, even - is the fact that the PlayBook lacks some of the most basic apps, including email, contact, a calendar, a notepad, or even RIM's famously popular BlackBerry Messager system.
