Erm, no, he didn't say it was a disaster. His review was quite balanced, praising the hardware and the support, but criticising the software as being complex. His conclusion was: "Overall, Apple Watch is exactly what I thought it would be: Expensive, unnecessary, and complex, but of obvious high-quality." which is of course true.
I find Paul is always very accurate, but he often either misses the point or doesn't explain his thinking very well. For a site which has a whole section dedicated to the Xbox, it seems weird to criticise a device as being "unnecessary", of course it's unnecessary, it's a consumer device.
