"All the drives come preinstalled..." with Sony's proprietary compression software that will only run on certain systems and won't be supported after a few years, might rootkit your machine, and near enough ensures incompatability.

Lessons well learned by everyone's favourite Prop-Tard (Prop-tart?) Company!

But does it work well? I've seen many a Sony product look good, then die in 6 months.

And what the heck is with these USB disks all coming with crapware now too? It's bad enough that some come with the crap, but the U3 stuff really ticks me off. Who said they could install fake CD drivers?
