When I bought my PS3, I would've paid a bit more for a backwards compatible model. >.>
Apparently most wouldn't care at all so SONY actually removed the BC feature to help out in the cost issue.
Only by then the PS3 started to sell well. That hurt the feelings of people who like features and understand that those cost money to make possible.
These companies are out for the money, not for pleasing people. Look how Nintendo doesn't think twice before going on suing people for petty reasons... lol It's always the money. (SONY also love to sue)
