Amazon.
Yes, all right, but I wanted to rent it, not buy it (though I realize my litany of brick-and-mortar stores-for-purchase probably made that unclear).
You can rent movies on Amazon for $4 and you get to use it for like 3-4 days.
1. I'm already paying for Netflix.
2. $4 is, like, Blockbuster rental price. Worked out really well for them.
3. What's this crap where I need a set-top box to watch it in HD? I'm sure the client's just a damn Linux binary; let me stick it on the computer I have hooked up to my TV, you dicks.
...truth is I'm not buying a whole lot of movies at this juncture (though I'm using the hell out of Netflix). Thing with DVD is, it's now the low-quality format; I'm reluctant to buy it for anything but TV shows made prior to 2007. (I DID make an exception the other day as Costco had the new Back to the Future Collection for $13. Which brings us back to the point of price.) Thing with Blu-Ray is, I don't know if it's still going to be around in five years. (Though if it is, I should at least be able to play it under Linux by then!) And the thing with digital downloads is they're DRM'ed. No format is really acceptable for purchase for most things, especially at current prices.
So for the time being, it's mostly renting and streaming. Netflix is good for those things! Maybe Amazon is too. I don't know, and I'm not going to pay $4 a damn movie to find out, no matter how much the studios artificially restrict the market.
