It really isn't important if the hint is technically wrong. The fact is resolution independence is coming to the Mac. The Mac now draws in points not pixels.

Absolutely not. Lion has actually taken a big step BACK from resolution independence. If you install the Dev Tools, you can scale the UI, this has been possible since 10.4. And Apple has improved this experimental function up until Snow Leopard, where even the three traffic light buttons were vector images and thus resolution independent. Now with Lion, they are bitmaps again. An awful LOT of stuff is now bitmaps again, just look through the /System folder. Stuff that could/should be drawn using Quartz is just images. I was really disappointed when I saw this.

The only sign of resolution independence in Lion is the "HiDPI" setting you can enable in Quartz Debug and then you get HiDPI screen resolution options in System Preferences.
