I did one of the early swaps to a new top with glass window back when they first came out and I had a 2000 Boxster. No brainer - go for the glass. You won't notice the visibility change after a week. It's not enough to have a negative impact.

I found that running the A/C on warm air was enough to defog the rear window in my case (don't deal with much frost where I live but I imagine that more heat and more air with the A/C could work on that as well). The interior of the car is small enough that just taking moisture out of the air helps. If you do want a defroster then look into whether your car was pre-wired for it from the factory as at some point I believe they started doing that in order for customers to attach the removable hardtop and hook up a defroster. If it was then you can get a kit that allows the glass on a GAHH top to be hooked up.

My info's old at this point but GAHH tops used to have the defroster lines on all the windows by default and it was just a case of whether you used them or not.
