How much the most iconic technology in history would cost today

The price for an IBM PC isn't correct (or at least, it doesn't match the infographic). The little picture shows a PC with two floppy disk drives and a monitor; the price quoted ($1565) was for the 16K model with no floppy disks and no monitor.

(And no hard drive, either). This means that the PC would boot into BASIC, and you could save/load programs and data to a cassette recorder. It was the absolute minimum configuration and wouldn't have been very useful.
