I got a replacement unit, too. I don’t think it’s any quieter or lighter, but this one no longer scratches up discs, either.
One bad thing about the replacement units — any XBLA content you bought will now only work with your original account, while logged in to xbox live. This may not be an issue, but for me means that the girlfriend can’t play the unlocked games with her account.
]]>1. the earlier revisions were engineered from simulation without a lot of empirical verification that things were behaving as expected. Manufacturer’s specs were off enough that there were too many problems and not enough time to fix them.
2. your new unit is lighter because it’s missing a couple heat sinks that you don’t need after having competent EEs do their thing with it.
