For me, the two things IPv6 does that I care about are

1) I get at least one globally-routable IP address for every machine on my LAN that I wish to have one.

2) I get multiple globally-routable subnets so that I can have networks on my LAN that are isolated from all other LAN networks, but are still able to have globally-routable addresses.

To make #2 work, you do need networking gear that's slightly better than bottom-of-the-barrel so that you can set up VLANs. If network gear vendors cared, they could pretty easily make those sorts of features standard in even bottom-of-the-barrel gear, but they do not, so they are not.
