Well, to each his own. But Nullsoft has even admitted that Winamp 2 is far better than Winamp 3. Winamp 3 is considered a failure by all concerned. That's why Winamp 2.xx is still so heavily supported, and is still being updated, and why hardly anyone uses Winamp 3.
It's not like I have a slow computer, and can't afford the resources that Winamp 3 consumes. It's that I don't want to. It plays movies... crappily. It also loads slow, is incompatible with existing plugins and skins, and doesn't behave in a suitable manner.
Winamp 2 ruled because it offered more features than WMP, and did so much faster and more smoothly than WMP. Winamp 3 takes all that away, leaving a product worse than WMP. If I had my choice of WMP 9, or Winamp 3, I guarantee I would choose WMP every time.
