I've decided that even if these things are $400 at launch (that's a pure guess on initial price), they will be cheaper per gig gained than a 60gb for $171 (going rate at pricewatch.com).

I have to replace my 48gb drive now. A 60gb drive will "just" barely get me going again, but will not really allow me any expansion past the amount of music sitting idle on my PC.

So..

60GB replacement for a 48GB yeilds 12GB additional storage for $171. 60GB = $14.25 per GB gained.

or...

80GB replacement for a 48GB yeilds 32GB additional storage for $400. 80GB = $12.50 per GB gained.

So I'll be getting a 80GB when they come out. The above math ONLY works if you can actually use the additional storage. Paying for any capacity that you will never need is a waste of money. I always say "buy it when you need it". Just look how cheap you can get a 60GB now! They used to be just under $400 and they will drop even more when the 80's come out.
