Another perspective:

Kinda like when you go to Blockbuster and rent a video game. You really don't care much for it, so you don't want to buy it. You would rather have the freedom to play it, then when you get sick of it, return it and forget it. If you still want to play, then you rent it again and again (probably would have been cheaper if you went ahead and just bought the thing). Sometimes you scratch it, you still return it and forget it.

But then you happen on this one video game that you really love to play. Well, Blockbuster comes calling they want their game back. But, you really really like it. So, you go to the store and buy the darn thing. You own it, you play it a lot, nobody will be calling to ask you to return it, and you tend to take better care of it. And, once it is all paid off, it's ALL YOURS.

Okay, probably not a good example...
