I'll be getting a macbook air soon and was wondering if I should always run on battery. Will keeping it plugged in constantly hurt the battery?

No & no (as long as periodic maintenance is done).

I'm not sure either. I heard it somewhere years and years ago. I had an old dell PC that was always plugged in and its battery got worse and worse the older it got. But that battery was Ni-MH i believe. So maybe with the new batteries it doesn't make a difference. Not sure.

Yes...battery technology has changed. All Mac's now have Lithium ion batteries...which are way different than the old nickel-cadmium or nickel-metal hydride.
