Has anyone else that plays D&D 4th edition tried the Adventure Tools?

They're still in pretty early beta and right now they only have the monster builder but so far it rocks!
No more searching through the monsters manual to find something that fits my groups level, now I can just find the monster I want and make it my groups level with the touch of a button.
Seriously, if you're running a 4th edition game this tool makes the D&D Insider price worth it alone. This coupled with the character builder and you just don't need to buy books anymore.
With this tool I made a large zombie black dragon in minutes that my level 4 group could handle.
Also, what do you think the four remaining tools are? I hope they are:
- NPC builder
- random treasure
- some sort of map tool
- some sort of adventure log
The only two downsides so far is that the interface is bad and it's a giant pain in the ass to install on Windows 7 (no problems installing it on XP).
