Will SSDs ever be as cheap as conventional HDD? Maybe, but not in the near future. As such, they will be "cheaper" but you will still have all those people who will say "but the price-per-GB is so horrible".
I don't know, when I had my SSD a while back (SuperTalent 30GB for $400), I liked the performance I got out of it. I didn't like the increasing "OS not detected" error messages and the lack of drive detection at boot-up. However, I suspect the new round of Intel drivers will help push costs down. If they can really save on power (and heat) with Windows 7, then I might consider upgrading both on my laptop.
