MG Siegler:

Is the PlayBook comparable to the iPad? No. Between the (lack of) app support and the wonky web browsing, there’s just no way around that fact. But RIM was smart to make the PlayBook a completely different form factor and give it BlackBerry Bridge to appeal to corporate users. So in that regard, there could be significant interest in this device.

The review isn’t as bad as the above passage makes it seem — Siegler notes that there were a couple of updates pushed while he was reviewing the unit and that the software has a lot of nice touches. The problem seems to be that the iPad 2 and the apps behind it are much further along than where the PlayBook is as it jumps in to the ring.
