No I don't work for Sony!

Nah, don't work for them!
Historically Sony have been more innovative, Microsoft just cashed in on gaming with the XBox, rapidly rolling out a buggy (and poor quality build) machine to get the jump on Sony's PS3 and cut a profit- good for MS but not for the punter, a pity.
Meanwhile Sony were willing to take a price hit on their console, putting faith in power of the Cell, built in wireless networking, quality and future-proof. Games like Uncharted 2, MGS4 and Grand Tourismo 3D are proof of this. With PS2 and solid games (Final Fantasy, Metal Gear, Racers, shooters etc) as a track record, choosing the PS3 was a no-brainer for me.

The XBox alternative was a paltry hard drive,(with overpriced upgrade option, no Blu-ray, and the audacity to charge for on-line p2p gaming, I started saving for the PS3 instead.
Sure the X-box has a lot going for it but the 33% fail rate (only now improving) was an undignified and disrespectful (to gamers) start and eliminated any chance of me having faith in the product as a long term consideration.

The PS3 is now in it's stride and will be able to make the shift to full and exclusive on-line purchase and gaming if/when it eventually happens.
It's common knowledge that some developers are putting out games that look better on the X-box but that is either their preferred console and/or laziness and not proof of anything else.

Exclusives aren't a problem at all and are becoming less so because there are fewer exclusives and more than enough quality exclusives to keep both sides happy.
