3D graphics boost is not going to happen if Intel's GMA IGP is all that is included on the MBA. I certainly hope the MBA gets marketed as a premium/luxury device again. I want BTO options back. I think with the iPad handling the secondary computing and lightweight entertainment role, the MBA can be repositioned as the premium device rather than trying to limit component upgrades to save on costs allowing the price to be dropped again.
The graphics are the problem/deal-breaker for me on this next round of Mac notebook updates. Assuming Apple uses Arrandale, and we know they cannot use Nvidia chipset/GPU combo with Arrandale, what do they do with the MBA, Mac mini, MB, and 13" MBP, and even low-end 15" MBP? Before we had Nvidia and 9400m across the board, now how does Apple tackle the Intel GMA IGP dilemma? I sure would feel stuck if all we get is Intel's GMA IGP... I couldn't bring myself to buy a computer that only had Intel's GMA IGP for graphics. I am hopeful for something even like the Nvidia 310m. It would be a 25% boost over the 9400m, so we wouldn't be going backwards. In addition, the system memory wouldn't be shared out. I know people are wanting a high-end ATI card like 5870 or even less like a 5830, but I see the Nvidia 330 GT making its way into the MBPs.
I sure wish we would have read some specifics like brands of graphics and other components being used. I don't see a 500+ GB drive making its way into an MBA.
