Unfortunately, Apple is very likely to keep the integrated graphics solution for the MB/MBA, just so it can distance the MB/MBA from the MBP.
Another unfortunate instance: Apple will still probably keep the Combo Drives... just so people who want to use iDVD HAVE to buy the mid-range MB. Apple will probably keep these Combo drives until:
a.) Optical drives lose their relevance. I see Apple's point with the MBA and their push for downloadable content with the Apple TV and iTMS/App Store.
b.) Blu-ray becomes a popular mode for optical data storage. BD drives get cheap enough so they become the new SuperDrives and DVD SuperDrives are relegated to being the new ComboDrive.
*when BD comes... what will they call iDVD?
I want Apple to stay with the MB chiclet keys... though the MBP keys are great, I think the chiclet keys are awesome and innovative. A couple of tweaks and I think the MBP people will be fine with it.
And LED displays for the MB!
*is the dithering/"lack of the millions of colors" problem still a problem with the current generation MacBooks?
Oh... and about the thread topic: PLEASE APPLE, upgrade the MBA Drives! The drive sizes are the biggest hindrance to the MBA being so much better.
