As far as I see it:
iPod mini
- Pros: Apple quality, looks, clickwheel >*, works seemlessly with iTunes for those who don\'t actually steal music, extras including games calendar etc, smaller, much more aftermarket support.
- Cons: Costs $10 more, 1gb less than the micro, no WMA
Zen Micro
- Pros: $10 cheaper, 5gb instead of 4, easier to change battery if fails, plays WMA
- Cons: A tad bigger than the iPod mini, more buttons on the face, no AAC
Notice this is the way I see it. Some may like the look of the Zen more which could easily go either way. Right now I\'m more in favor of the iPod simply because of all the comapnies that make adapters for it to work in your car.
