Ok, you asked for it.

This should answer the question "What was the first personal computer?"
once and for all.
Ah, but what was the first Microcomputer (including at least a monitor with
bitmap display, some sort of disk or floppy drive, as standard features,
and 'personal' in nature)?
Or what would your definition of Micocomputer be? I suppose we have to
establish that first. graphic monitor and floppy drive, with hard drive
optional, would seem a good start.
