Not sure if it counts as a specific generation, but I hated all that Spectrum, Amstrad, Atari and Commodore "Home Computer" shit we put up with in the UK in the early 80's.
They were, for us, the machines that superseded the whole 2600/Colecovision/Intellivision phase, prior to the NES & SMS taking proper hold.
I had a 2600 growing up and then "advanced" to a Commodore 64 with cassette tapes. Piece of shit btw.
Then the whole Amiga 500 & Atari ST era kicked in shortly afterwards. Now, to be fair, the A500 DID blow me away at the time, being able to play stuff like IK+, NARC, Ninja Gaiden Arcade etc at home, with those graphics PRE MD & SNES era... was impressive.
But my beef isn't with the Amiga etc. That was alright.
That pre-16 bit (i.e. the 8-bit) home computer period was utter shite. Not too bad NOW with the modern upgrades such as the use of flash cards etc, but if we appreciate it at the time it occurred, it was horrible. SMS, NES then MD & SNES couldn't get here soon enough for me. I never looked back after that. Ever.
