I really don't get homegroups. Before Windows 7 I've shared files across the computers in my home using networking. Networking is very easy to set up. It's very easy to identify the files/folders to share via networking. And, networking doesn't restrict the files shared to only libraries.
What am I missing? Why should I use Homegroup instead of standard Networking?
I have a home network with four computers.
Windows 7 build 7100 RC
