Is SUN One Studio free ?

In http://wwws.sun.com/software/products/appsrvr/appsrvr_download.html
The first download stuff "Java System Application Server Standard Edition 7" shows it includes "Sun ONE Studio 5, Standard Edition" and it is 60 day trial version. So this seems that the SUN One Studio 5 is free (60 days).
However, when I go to http://wwws.sun.com/software/download/products/3edd36bd.html it says the license version is $695 and no-license CD is $20.
So,
1) what's difference b/w a "license version" and a no-license CD ? If I paid $20 and get a no-license CD, can I install it on multiple PCs ?
2) If I use first link http://wwws.sun.com/software/products/appsrvr/appsrvr_download.html and download the first one, does it mean I can still get a free SUN One studio 5 for 60 days free ?

It looks like Sun is providing a free development licence for the application server, but only a 60-day trial licence for the IDE.
Would it be better to choose NetBeans or Eclipse instead (i.e. how much do you value the integration with the Sun appserver)?

The CD is just a convenience if you don't want to download the product.
You pay $695 for the product itself, and ANOTHER $20 for the CD-ROM.
