Yahoo Webhosting

So, I was working on a clients site today and noticed that yahoo gives both unlimited disk space and unlimited bandwidth usage for ~12$/month.
Has anyone ever used this? I mean there has to be some sort of catch here that I'm missing....

With that said, I host everything myself, but it would be nice to host large (er) files off site. (Such as video tutorials, any programs I make, etc).
I just read the TOS and it says that you can't use it for commercial purposes.

They probably don't support shopping carts / SSL / something of the sort for a commercial site...

It'll be geocities without the ads. :afrog:
