Coming to the end we can say that the Apacer drive is extremely well designed; its blade function allows it to maintain a small profile along the side or back of a notebook without getting in the operator's way.
While it does support ReadyBoost under Vista, we didn't notice any performance increase in our tests at all, so really this is a mute argument at best.
If you're after a backup and security solution, this drive is definitely what you're after. With its advanced compression software you can stick a bit more into it than your normal USB flash drive. Good on you Apacer.
