Yeah, I read about it last week, seemed like a bad business scheme to me. If home rentals made sense, amusement places would be offering this a long time ago. Dealing with 1 cab per place, having to rotate it out monthly, deliver all over San Francisco and move it into peoples homes that may or may not be cabinet friendly, deal with maintaining these and keeping a large enough inventory that customers will have choices. Making $7500 per 100 customers seems to be barely scraping together any profit, and a ton of work.
I am also guessing that the bigger issue than damage would be people gutting out the valuable parts. I just don't see the delivery guys being able to examine each machine to make sure every part is the same as when they left it.
$10 bucks says that 9 of 10 machine you would rent would smell like cat urine or worse.
