One reason would be space. I currently have a 120gb SSD which has about 12gb left on it. I did not install much on that except what was already on it, and a few apps like iTunes. I already moved my Desktop location to my hard drive and will do that to the other recommended changes as well. I know it's not recommended but I messed with the registry and changed the locations of my program files. If you think I do not need to change anything then I guess I won't. A possibility for me would just to buy a larger SSD. But I thought changing the location of the users folder would fix my space problem since it's a big folder. But after reading what you had to say I see that I shouldn't.
Right.
Space is a typical issue with the 120GB SSD's.
You can redirect all your Libraries (Doc/Music/Video/Downloads) to other drives.

That's no problem. The whole /Users/ folder WILL be problematic.
Changing the default Program location in the Registry? Another bad move, and completely not needed.
I expect things to break on you during the next semi-annual update.
During an application install, you can tell it what drive or folder to install it to. That's no problem.
Moving the whole Program files thing to elsewhere? Problem.
In reality, though, applications don't take up that much space.
Games do, but again, that is easy to manage.
