That's not a fact. It's an opinion, and a biased, ridiculous one at that.
Opinion? Yes. Ridiculous? No. I am not a fanboy and I do have an appreciation for both MS and Nintendo, but when comparing what Sony provides to its gamers (especially compared to Microsoft) there is a big difference.
Sony does not charge for its online service. Microsoft does not even come close to producing the same number of exclusive games for its system as Sony.
The comparisons to Nintendo are more difficult and may not be as valid, but many people would agree that Sony is geared more towards hard core gamers than Nintendo is.
Again, I like all three companies and have no loyalty to Sony. I would just hate to see them out of the picture.
