The Playbook does have it's limitations, mainly lack of native email and calender (to a lesser extent no BBM), but for $199 I don't think there is a better tablet.
From what I've read, Playbooks are flying off the shelves with the $300 price cut. So that just shows that at full price, people aren't willing to buy. But for $199, the Playbook is a great budget browser/media player. Because in those regards it is at least competes.
At only $199, we need to compare it to it's similarly priced competitors, namely the Kindle Fire, Kobo Vox, and the T-Mobile Spring Board. On a side note, RIM claims it is committed to the Playbook, so this isn't a 'sinking boat' sale like the HP tablet failure. The Playbook will also be able to run Android apps once BBX comes out. There's a lot of reasons to give the Playbook a chance, especially for so cheap.
Anyways, anyone aware of it's line-out capabilities? The Playbook is able to run an HDMI out, I'm not sure if that means anything regarding the line-out.
