I'm still waiting for Lion to be released on DVD.
You mean the film from India (2006)?

Pigs will land on the moon before Apple breaks down and puts Lion in a round lucite/aluminum cage.
But seriously, consider this OS release as like HD management software, like Drive Genius. ProSoft makes a downloadable DVD image available (to registered users), and they can burn it onto a cheap blank DVD, or a dedicated partition or drive. As often as desired. DIY.
Apple is nudging the IT industry slowly away from mechanical storage, and towards storage in silicon alone. Optical storage relies on moving parts, and Steve et al. would rather have just the electrons move, and nothing bigger. The announced USB stix are the first big nudge.
Leopard users could conceivably share the cost of a clean Lion download with a Mac neighbor, and extract the standalone disk image (easy to find out how)—then skip Snow altogether. Skirts the EULA. Your results may vary.
I got a slight discount on Lion by buying two $15 App Store gift cards (10%—15% off, I forget) at Best Buy last month. Redeeming them at full face value is the cheapest way to get a hold of Lion. Legit. Won’t download until I read more, though. The USB version of Lion will likely be 10.7.1 or possibly .2.
