Yeah I'd love one, never really cared about companions and whatnot until Dogmeat...
Poor little guy, sent him off to find ammo and didn't see him for days... then during one of the final quests he came running, taking on as many Enclave as he could - only to be gunned down trying to protect me
Haha but no seriously I'd like one so long as handling them is better than companions have been previously; sure NV improved on them but it still wasn't great, especially having to be next to them to issue commands...
Hopefully they can come up with something for companions.
