I'm wondering if inverter microwaves are any less reliable than
traditional transformer/capacitor types.

Since they're a relatively new technology (at least at the consumer
level), my suspicion would be that, yeah, they are a bit less
reliable.

BTW, once the microwave is sitting on my
bench top, the extra weight of a traditional mains transformer is of
no consequence.

There's also a bit of savings in lower freight costs from the lower
weight.

the savings is in not having to build an expensive,big transformer.
all that copper is expensive,too.

And smaller people (women in particular) tend to put some
emphasis on the weight of their kitchen appliances, even if (as you
point out) it's often completely irrelevant once you get the thing up
on the counter at home.




transformers,being far less complicated,are more reliable.
Inverters have a lot more components,particularly electrolytic caps,that
increase the odds of failure.
Many electrolytics are only rated for 3000 hrs or so of operation.
and it seems that surface-mount electrolytic caps are even less long-
lasting.
