The Vic 20 had these great cartridge games, which made up for the paltry memory. The Commodore 64 was a game changer, as I recall.

Yes the Vic 20 did. I got the 16k memory expansion card. I also had the alphacom 42 thermal printer. The 64 Did nor have many cartridge games but by then I had the disk drive. remember using a hole puncher to be able to use both sides of the floppy disk?
Good times
