I work for an IT hardware reseller (mostly; we do some new stuff too), so scrounging up some lab boxes or test beds usually isn't a problem. I've got one in our rack right now that I fire up to mess with VMs via Hyper-V, rather than adding a bunch of extra load to our ESX cluster. And we mostly deal with smaller development projects, not spending months building huge software packages, so it's generally not too hard to grab a few hours of downtime here and there to read and experiment with stuff. Our dev team (a whole two of us) have MSDN subscriptions, so it's open season on learning MS products and figuring out what might be useful to us.
Thus, I don't have a ton of experimental IT gear at home, nor do I feel all that compelled to continue doing at home what I do all day at work. I've got a desktop that does a few light server duties, and which is mostly just a means to and end. I do have a growing pile of assorted tablets, though...
Personally, I think the answer might be a hybrid situation. EG. Offer physical DVD rentals out of an existing establishment that's already successful on its own - like a gas station, bar or grocery store.
So Redbox machines, basically? I see quite a few of them around here.
