I don't doubt that 8GB is enough for most uses today. But is it closer to "more than enough" or "just barely enough"? Seems unlikely to be the former at a price point this low.

Five years from now, I have no doubt that the processor will still be fine for most uses, but I doubt that 8GB will be. Especially given that some of the most common memory hogs aren't under Apple's control (cough Chrome cough).
