What would you rather have: A Hard Drive or Backwards Compatibility?

[HappySqurriel]

Personally, for the PS3 I would rank removeable features (in terms of importance) as

1. Hard-Drive
2. Backwords compatibility
3. USB ports
4. Memory Card Ports
5. Blu-Ray movie playback

Sony would have saved a similar ammount by dropping the Blu-Ray licencing fee as by dropping backwards compatibility.
