I've heard also that G4 is crappy, that all their info is false, and that Tech TV's shows are bad. Is this true?

Is there even such a thing as an absoute truth? Before we can know if anything is true, we have to also know what "truth" is. So I will ask you to kindly define truth below.

Lol! It is true that most reviews of products are biased on the reviewer's views, beliefs, opinions, etc. What one person says is good, another will say is bad. For technology, it can be tested one way and show itself to be high quality and tested another way and show itself to be low quality. The only way to really get a good review of something is to look at many reviews and compare them. If the same things come up in all the reviews, they are probably accurate. If not, then you should question them.

wouldnt know. only you can decide for yourself.
