I tend to agree with Rob, although for slightly different reasons...
I don't want to come across as an industry stooge or anything, but I really think you should feel a teeny bit guilty if you buy anything but the manufacturers proper replacement cartridges. After all, they did all the original work in developing the thing - if you're happy with your printer generally then why not think of the premium you pay for the "real" catridges as a charitable donation towards the continued development of improved printing technology!?! You'll get a nice warm glow inside...
Similarly, music and software piracy kind of p1sses me off. Unfashionable, I know, but there you are. I heard a friend recently saying that he was really keen to get his hands on the new Blur CD, but he had to wait a while as his other friend hasn't had a chance to make him a copy yet. This guy isn't short of cash or anything, he's just trying to beat the system - naughty!
On the other hand, if he didn't really like Blur but his friend made him a copy anyway and said 'go on, give it a try, you might like it', I wouldn't mind so much. The difference is that in the former case the guy would buy the CD if free copies weren't available, therefore he's done the record company out of a sale. In the latter case, he wouldn't have bought the CD anyway, so no-one's lost anything.
The world of CBLong morality is a murky place...
By the way, guess which type of copying the industries base their "cost of piracy" figures on??
