Macbook is now dead, period. There are rumors of a Macbook Air 15" circulating, maybe even a 17". With chips becoming more efficient and producing less heat, isn't it feasible to say that within a year or so, we could see the Macbook Air and Macbook Pro lines converge altogether? So we would basically have an 11", 13", 15" and 17" Macbook Pro? "But Macbook Pro's need top of the line CPU's and Macbook Airs can't fit these CPU's TDP and heat in them!" - True, but looking at CPU/GPU roadmaps, chips are producing less heat and are becoming more efficient. Maybe not this year, but by 2012 or 2013. The Macbook Airs now haul some serious *** compared to their predecessors. Who knows what another refresh could do to them in a year or so. "What about the Optical Drive?" - Judging by the fact that Apple doesn't sell CD software in stores really anymore, or distribute their OS in this fashion, it's safe to say the Optical drive will be killed off at least in their notebook line by the next refresh. I think it's finally time. Plus, this would make a Macbook Pro able to be thinner as there is more real estate for heat dissipation or other components. "How is it a pro machine if I can't upgrade my RAM or HD?" I do think that as the Macbook Air line becomes more widespread, Apple will engineer them more in a less restricted sense. The technology for RAM and HDs in the Airs currently isn't revolutionary per say, but it's not common enough for many aftermarket alternatives. Maybe the 11" and even 13" will stay un-up-gradable, but surely with larger space the 15" and 17" will remain up-gradable. I also think we will see the 15" and 17" retain some sort of mechanical HD or non-blade SSD for the majority of their storage, and the same type of blade SSD as seen in the 11" and 13" for OS and core components, ect. Thoughts?
