i had the same question before I bought my mbp and IMO the cost difference isnt that much when you're buying a nearly 2K laptop, so I just went for it, and I have to say this is one damn good screen
My hi-res antiglare arrived today and have to say, it's definately worth the upgrade. do alot of work in the adobe creative suite and the extra space is always welcome for palettes etc. working across the new one and an old 2007 mbp at the moment and the menu bar looks huge now on the regular screen!
Though, having said that, i also only has the option of an anti-glare model - can't stand those glossy screens; i like my laptops portable and the reflections just don't cut it. only have to walk into the covent garden store when its getting dark and they have their overhead lights on and look at ag next to a glossy to realise just how shiny they really are. though each to their own.
you are correct. Glossy screen both hi-res and regular comes with the black frame. The Antiglare (aka Matte) screen comes with the silver bezel. I'm sorry if I confused you but I think i was pretty clear in my previous posts 😕
