Mac OS X Lion: Coming In July For $29 (And You Won't Be Able To Buy It On A Disc)
And there’s another significant piece of news: you won’t be able to purchase Lion in retail stores on a physical optical disc, as it will only be available as a download via the Mac App Store. The download will weigh in at around 4 gigabytes, or around the size of a movie.
The developer preview will be available today.
This isn’t actually the first time Apple has offered an OS upgrade at a steep discount compared to its Windows rival (which typically runs over $100) — Snow Leopard made its debut at $29. But that was considered more of a stability and performance upgrade as it didn’t have many new features; Lion is packed with additions.
