In 1981, I convinced my parents to buy a used Apple ][. That was ??my? first computer, though really the whole family's.
1 MHz 6502, 48K of RAM, no hard drive. Initially, we only had
an audio tape recorder to save and load programs and data, though
we soon added two 140K floppy drives.
The first computer that was truly my own was a brand new Macintosh ][, which I bought in 1987.
16 Mhz 68020/68881.
I inititally bought it with no hard drive (later added a 45-meg drive,
and after that died, a 200 meg drive), two 800K floppies (later upgraded
to two 1.44-meg floppies) 1 megabyte of RAM (later upgraded to 8
megabytes).
My current system is a Beige (Pre-iMac) Power Macintosh G3.
300 MHz PowerPC G3 processor
352 megabytes of RAM (recently upgraded from 128 megabytes)
6.4 gigabyte hard drive
10 gigabyte hard drive
MacOs X 10.2.8 ??Jaguar?
I paid nearly $6,000 when I initially bought my Macintosh ][. Looking at Apple's current offerings, it looks like, if I had that much to spend now, I could buy TWO of their current top-of-the-line dual-processor G5 systems. Alas, I'm not nearly so wealthy now (at least not in terms of excess $$$) as I was in 1986. My current system, I got for about $200 via eBay, earlier this year.
