I fully agree... out of everyone at Pocketnow (which I think is a great site), Jaime is the only one I dislike. I'm totally open to criticism of Windows Phone, but he is just so arrogant and eager to dismiss the platform. To me, he comes across as a total d-bag.
If you check his most recent posts, they're all about dismissing Windows Phone or Windows 8. I can't stand reading his posts so I simply don't bother anymore.
I'd rather read The Verge or Engadget's take on a Microsoft product than anything Jaime writes.
Other than Jaime, I like the rest of the gang at Pocketnow. I visit the site daily and enjoy their videos (especially those of Michael Fisher and Brandon Miniman).
