I am absolutely impressed. I had never seen a one CD distribution like the latest Vector release.

For a lightweight distro it has almost everything you can desire.
The care of details is absolutely amazing.

For a slightly older PC you'd be hard pressed finding anything better. But also on a modern, powerful box it wouldn't be out of place.
In any case everybody should try it. If a small team can create such an amazing OS, what could people with money and manpower do? (and they don't, in most of cases).
