It has long been suggested Apple is just waiting for Resolution Independence in OSX to offer higher density displays on their laptops.
Unlike choosing a smaller monitor resolution, which on LCDs makes things rather fuzzy and blurry, Resolution Independence simply draws user interface elements and text bigger, so it looks the same size as a lower monitor resolution, but actually uses more pixels (at the LCD's native resolution) with the added benefit that text and UI elements will look sharper.
With Resolution Independence 15" MBPs could easily have 1920x1200 resolution displays while users can dial them to look like 1440x900 resolution - just 'sharper'.
Best of both worlds!
The drawback is that the OS must have the power to resize UI elements. And not every software plays along. Many draw their own UI elements with their own drawing routines - none of these would scale things up nicely with RI on. The result being a messy mish-mash of nice and ugly/small interface elements. Not good.
So RI was included in OSX 10.4 already, but low-level for programmers to gain experience and test their software.
The promise was that OSX 10.5 would include it.
Initially Apple announced RI as a feature for Leopard. But later removed it.
Will it finally appear in Snow Leopard?
The lack of an official Apple statement doesn't give me much hope.
It's a shame really. I think many more buyers would consider a higher resolution built-to-order LCD - if they could choose a virtually lower res (with added sharpness) for applications where they don't feel comfortable with smaller UI and text elements.
But if it happens there is a glimmer of hope that the next MBP revision, well after Snow Leopard, will finally see higher resolutions. October/November?
Anyone know anything more about the state of RI in Snow Leopard?
Will it happen?
