Yes, all the time.
I steam all sorts: tofu, tempeh and vegetables, to name just a few. I'm not a huge fan of the microwave*. Our current microwave is a very small one that cooking much at all in it is difficult. Even sweetcorn cobs are a challenge because they are often too long for the turntable to go round.
We've a single layer adaptor to one of our IKEA pans that came as a dedicated steamer and we've one of those weird metal flower bud inserts that acts as one as well. I've also been known to use the pasta pan insert as a vegetable steamer as well (my parents bought it from my money when they were stranded here & everything got left to me when they finally managed to get back home).
I'm considering getting a bamboo steamer as well to be honest because I often find that here are items that would steam better if the stream holes were better distributed.
I pretty much steam most things because it uses less water which from my point of view it's a good thing (i know microwaves use even less but i don't like microwaves or clingfilm which is bad for the environment, though there is now a biodegradable version just on the market) and also with it taken marginally longer than boiling the veg, it's less likely I'll over cook the veg through losing track of time. We have a timer, and I use it but I'm horrendous for setting the time and forgetting to press start...
* (Bad experience with one melting down, and me being left with the choice of staying put, to turn it off and ending up toxic fume inhalation and a severe asthma attack that came close to killing me (I was resuscitated in A&E) or leaving the maisonette and burning down the block of 10 houses we lived in.)
