3D modeling is something I know absolutely nothing about. As such, I cannot really give advice one way or another on DAZ Studio 4. Instead, I ask dotTechies who do have experience with 3D modeling give us feedback regarding DAZ Studio 4 in the comments  below.
I will say this much, however. DAZ Studio has three different editions — DAZ Studio 4, DAZ Studio Advanced 4, and DAZ Studio Pro 4. The following are the differences between the three editions, as per the developer:

This freebie is of DAZ Studio 4 — not Advanced or Pro.
DAZ Studio 4 is being given away in a promotion by the developer. The giveaway is live until December 31, 2011 but there is no information on if you can install/reinstall at a later date. My guess is you can install/reinstall at a later date because the freebie is being processed like you are purchasing it (although you don’t have to enter any financial details).
