It's a bit hard to take CNN seriously as a tech commentator, frankly. They published this today: http://www.cnn.com/2011/TECH/gaming.gadgets/03/03/missing.fr... I've rarely seen a tech article that was less useful or more silly.
Not sure why you chose to justify criticising CNN with a single article that was written by a guest, who happens to actually work for Mashable. I don't read CNN regularly so I won't argue for or against CNN's tech coverage, but if you want to argue against it you should try a little harder.
The author tries to pretend that sales "into the channel" are real sales (they aren't, of course). He pretends that all RAM is equal and directly comparable (on-die RAM is clearly superior). He pretends that megapixels in cameras that are a few mm in size is a hugely important measurement of camera quality (it's not). He pretends that the Nook and Kindle are at all comparable to the iPad or even in the same product category (they manifestly aren't). He pretends that all dual-core CPUs are equivalent (which is laughable).
I can't remember the last CNN tech article that I found to be insightful or informative. By contrast, I read a few dozen things via Hacker News daily that pass muster.
