JBL creature questions

[JaGWiRe]

Hey, I was looking into JBL creature speakers but have a few questions.

1. Do these work with windows comps as apple store doesn't say anything about windows and only mac comps.

2. If not, are these worthwhile for my ipod.

3. Are these better than my current computer speakers?

4. I have an IMONSTER SPLITTER, does that mean I could have both speakers at once running on my computer or ipod?

Edit ::

5. Are these speakers better then the creatures or both systems?

Creatures work with any thing with a mini plug. They are pretty good, but if you want great speakers, get klipsch 4.1. You can usually get factory restored ones on Klipsch's website for $99 bucks, and they will blow your mind!!!! They are hookesd up to my computer, and everyone thinks I have a thousand dollar system.

Should I buy the invaders or creatives?

Which are better?
