Check your water to see how bad it is: sprinkle tap water on things and see if it's tolerable. If it's bad, you might be able to beat it with filtration. And even if you can't, you can always be a little more diligent about drying the sink.

I think it sounds fabulous and is worth trying to make it work. And stainless spots almost as obviously as black. If spotting is really bad, maybe glossy white to match the cabinets?

Get a Blanco Silgranit sink :). The Anthracite color is extremely easy to keep clean. Ours is about one year old now and we just scrub with a little bit of dish soap on our brush and rinse.

Here is our main sink:

Since your profile shows you are in the UK, you have different selection of models than we do in the US but the Silgranit material really is wonderful

Here is a link that might be useful: UK Blanco site

I love your black sunken sink - it looks great! I am going for black slate effect laminate worktops, so can't have this design.

I think the comments are correct - if I went for stainless steel I would always be thinking about the black option!!

If I was clever enough on the computer I would up load a picture of what I am thinking about!! But I'm not!

Thanks!

If you look at the UK Blanco site I linked, it looks like many of the models should work for laminate.

I would enthusiastically second daki's recommendation of Blanco's Siligranit sinks. We have an undermount installation similar to daki's, also in the anthracite color and it is hands-down the best, easiest-care sink we've ever owned, and we've had all kinds. To answer the original question, FWIW we're on moderately hard well water and along with the sink have matte black fixtures, no water spotting issues with either. As daki points out, Blanco has "overmount" models as well as "undermount" ones, so you should be able to find something that works.
