I have my Olympus Trip, bought new back in the late 70s or early 80z, can't remember when.
Also Olympus E500 and E510, EPM1, EPL5, EP3, EP5, OMD EM5, OMD EM10, OMD EM5 Mkiii and
Panasonic G6, Panasonic DC FT7 and
Samsung WP10.
As you see I don't throw things away. I have about 40 lenses, many from extinct SLRs and DSLRs bought cheap. All the adapters I have mean that they can all be fitted to and used by my MFT cameras, and many by my 4/3 E500/510.
They all work but the quality of the older 4/3 pair and the G6 is less than acceptable, and probably always was.
The Samsung Waterproof has been replaced by the Panny DC FT7, both are rugged and bought for use while cycling.
My hobbies include wildlife, street and landscape photography, and apart from the 4/3rds cameras and the EPM1 and G6, all get outings throughout a normal year, whatever one of those is.
