While it doesn't replace the need for complete research, what a number of people are going to do is ask a sales clerk (as a previous post mentioned as a common question) if the PS3 is BC. How many sales clerks will know the correct answer is: 'It depends', and then be able to explain it correctly?
And FishyJoe, sorry. Messing up your research is just a bad as not doing it at all. You're banned from all video games systems for a month! And just lucky we don't make you return them all.
Hmmmm... How bad would the console sales be if you needed to take a test and pass it before you could buy the console?
Torturing the numbers. Hear them scream.
