[Metricon]

My first computer was a TRS-80 MC-10: https://en.wikipedia.org/wiki/TRS-80_MC-10 A less expensive version of the TRS-80 Color Computer. The worst part wasn't the 4k of RAM, but that I had no storage device for it so would spend entire days writing programs only to have to turn it off and lose it all.

Thankful, less then a year later I went the Commodore route starting with a VIC-20 with a cassette drive, then C64 with a floppy drive, then an Amiga with a hard drive before fulling moving into Wintel PCs in the 486 era.
