Re: SSD benefits
I think we already passed the point where SSDs make more sense than hard drives in laptops about five years ago, personally.
The question wasn't whether replacing the single hard drive in a PC or laptop makes sense, but whether ALL hard drives would go away just because of the speed advantage. All those hard drives at Facebook, Amazon and Apple storing cold data won't be replaced by SSDs until they are cheaper per bit, because no one cares if it takes a few seconds spinup delay to open that photo from 2007 that no one has looked at in eight years.
