My work-provided iPhone 4 is getting on in iPhone model years. It has 512 MB of RAM, which is twice as much as it’s predecessor the 3GS and four times as much as the original iPhone, but only half as much as the iPhone 5. For a three year old smartphone model, 512 MB is okay, though that’s not much at all by modern personal computer standards. Still, I find it interesting that 512 MB of RAM in my iPhone is 128 times as much as was in my family’s first Windows PC in 1990, and 256 times as much as was in that little IBM PS/2* that Neil Patrick Harris used to tap out a journal entry at the end of every episode of Doogie Howser M.D.
* IBM PS/2 as in the computer, not to be confused with later incarnations of gadgetry to be nicknamed “PS2.”
