I'm always intensely curious what residential (and these days, even business) customers want with a dedicated, publicly routable IPv4 address.
why were you disappointed?
I wouldn't use it for anything too resource-intensive or important. It's just nice to have my home development environment available over SSH for the rare coding emergency. I shouldn't exaggerate how disappointed I am. It's obviously not very crucial to me, since it would be easy enough to set up a cheap VPN for tunneling but I haven't bothered to do that yet.
