I could download all tracks from YT free, but I wouldn't have the CDs and the nice box. i saved my money for months and it's quite hard to decide if i should spend some in a soundtrack thats free downloadable...
You get the pretty box, and it's a collectible that CAN be hard to find a decade down the road. And you support SQEX financially, allowing them to make more games you'll enjoy in the future. That's about it. Personally I've never put my soundtrack CDs into a dish tray once, and if you're not a collector, then don't buy it.
If you have no financial constraints though, I don't see why not. But if you do, then perhaps the money can be better spent elsewhere.
