Why do people make such a big deal about backwards compatibility?

[Adameh]

Backwards compatibility is important to me because:

- I only have 2 HDMI ports and one AV port, and I can't be arsed to change the ports all the time
- I only have a couple plug sockets
- Standby energy consumption
- Only enough room for four consoles
- I don't own the original Xbox, Gamecube or PS1. No problem! I have the sucessors

If my Wii U, Wii, Xbox 360 and PS2 all didn't have backwards compatibility, I'd need a Gamecube, Xbox and PS1 as well.
