O god... intel HD 3000. Intel graphic card will never get into my house. Ever. Ever Ever Ever EVer Ever again.
I enjoy the enthusiasm against Intel's IGP. I cannot stand it, and the track record in the MBA should show people they need to do their homework before begging for an Intel IGP in their next MBA.
Someone else asked about CPUs. The 11" use SU series while 13" use SL9x00 CPUs.
Apple could use C2D in the MBA through 2012 if it wanted to. The C2D will be made for many more months and Apple could stockpile chips for its MBAs. Heck it has been using the same SL9400 for years.
Lastly, check the real updates to the MBA. The June update wasn't really an update. Intel added the SL9600 at same price as SL9400 was before so Apple shifted the CPU for thar reason. In addition, it bumped the battery ever so slightly to meet some energy rating and threw in an Ethernet adapter and called it an update. It wasn't a real update as the other three models offered new chipsets and etc.
I think people are going to be terribly disappointed if they're expecting a Summer update to the MBA. In addition, the Intel IGP performs at a much lower clock speed in low voltage SB variants. I don't know that Apple can stick MBA users with the Intel IGP in its current form at that low of clock speed as it could represent worse than half the current capabilities of the 320m. People are treating the Intel IGP like it's the same in low and ultra low voltage chips, but it's actually far less capable and possibly not even as capable as the 2008 9400m.
The MBA represents much more speed and capabilities than a STD C2D CPU notebook. Apple attacked what is really wrong with computers today, drive and drive controllers and software. I will gladly use my MBA and hope for a much better overall update than Intel's SB can offer. I really think an Ivy Bridge MBA makes more sense than SB. What makes even more sense is AMD's CPUs with IGPs on die down the roadmap. The newest info shows higher voltage variants but when the low voltage variants come they will possibly offer 5x the graphics capabilities from the same TDP. I really hope Apple introduces that line of AMD LV chips in the MBA. It is less likely than Ivy Bridge but I believe more likely than SB.
