A lot of the critique is actually high praise...
if you compare this device to Android tablets like the Xoom or Galaxy 10.1.
The battery life is probably on-par, the WebOS is much better than Honeycomb, and 300 apps? that's like 3x as many as when the Xoom (or even Galaxy 10.1) had on release.
There is no tablet market, only an iPad market.
However, if I was going to anoint one halway-decent competitor to the iPad it would be the Touchpad.
