Submission + - BlackBerry Playbook Impressive, But Unfinished (ibtimes.com)
The PlayBook lacks a number of seemingly essential features common to competitors, including a native web browser, email client, significant app support, and, (inexplicably) its own BlackBerry messenger. While RIM makes much of that missing functionally available via BlackBerry Bridge, the lack of built-in support for the features is, as one reviewer put it, absurd.
But all of that underscores something common to many device makers. They are all, at launch, unfinished, awaiting upgrades that often come months later.
