I don't get what all the hype is about. I bought a used model M from ebay, and the keys were much harder to press than a cheap squishy keyboard.
I briefly used what I realise (in retrospect) was a Model M keyboard at a job I had in the late-90s. At the time I found the fact the resistance was half way down and very obviously "click switchy" (i.e. requires relatively high amount of pressure to get through, then suddenly breaks) to be strange and unnatural. I'm no millennial membrane-weaned weenie; I'd been using computers since the 80s, most of which had mechanical keyboards back then, and while some had been mediocre, some I really liked. They all went "tap" at the bottom, unlike this weird and unsatisfactory action. I have to say that Model M did nothing for me, and I'd no desire to return to it.
When I bought a Cherry mechanical keyboard for myself, I intentionally avoided the ones with the Model M style force gradients in favour of the ones that go "tap" at the bottom.
I've said it before here, and I'll say it again- the people who like Model Ms seem to *really* like them, but I'm convinced that the majority of people who didn't grow up using that keyboard or anything like it would- at best- find it an acquired taste, and probably be happier with one of the better membrane jobs (sacrilege!) or a mechanical keyboard with a more regular action.
I also think that membrane keyboards nowadays aren't that bad. Maybe I'm just used to them, but while I've come across some truly horrible examples at the dirt-cheap end, I've also come across some that were quite pleasant to use (and oddly, were also dirt-cheap models). Still not quite as good as the best- in my judgement- mechanical keyboards, but much better than the mechanical keyboards on some 80s home computers.
Anyway, back to the Model M. Yes, it feels "expensive" and "well made" in that it's obviously mechanical, and heavy, but that doesn't make it that great to type on IMHO (any more than I'm going to deny that my membrane keyboard at work is okay, simply because it's cheap). Some people think they're really great, and that's fine, they're entitled to their opinion. However, given that the borderline fetishisation from a disproportionately vocal number of fanboys might give others the impression the Model M was the be all and end all, I'm quite happy in balancing things out by saying I don't think they were all that, to be honest.
