RIM may want people to compare its PlayBook tablet to the iPad, but journalists have a less complimentary comparison for the device.

[ad#Google Adsense 300×250 in story]While I was attending WWDC last week, CNN said the PlayBook was the “herpes of tablets.” Apparently the news organization was trying to return the PlayBook to RIM and got no response.

CNN thought so little of the PlayBook that they would pull it out when really bad products were sent to them and say, “But at least it’s not as bad as the PlayBook!”

Surely even those people that gave the PlayBook some slack for not including email, calendaring and basic Internet connectivity, must be reconsidering their position.
