The real irony is Apples so called "Hi-Res" is not hi-res anywhere except in AppleLand. Likewise it's only the latest & greatest in Apple Speak.
In the PC space, there are three resolutions for 15" displays that have been offered _for years_ on ThinkPads & others.
Stepping out of the Steve Jobs "Reality Distortion Field" the facts are 1680x1050 is medium res, 1920x1200 is high res.
It's "Magical & Revolutionary" ...![]()
Apple may call it whatever they want. 1680x1050, *for me*, is uncomfortable for prolonged use on a 15" screen reading text, specially browsing the web, as almost all websites appear with tiny text in cmd+0. As is 1920x1200 on a 17" screen. Maybe 1680x1050 would be passable on a 17" screen, but for me, not on the 15", for sure.
But as I said, that's my personal experience on the subject. Maybe someone with better eyes could could argue otherwise.
