My best friend's mother had this arrangement in her last house. We went to their house regularly for holidays and the corner sink sucked. When cooking and cleaning, you could NEVER have two people use the sink and if one person was doing some prep or clean up by the sink, it completely cut off access to the only sink/water in the kitchen. For anyone else to use the sink or get water, the person had to move away, and it wasn't just a quick step to the side, it was always several steps to get out of the way. The dishwasher was next to the sink and if the dishwasher door was open, it further restricted access.
Since I entertain a lot, corner sink was a non-starter. I suppose if you had a single person or a couple where one did not do much in the kitchen, it could work, otherwise, too much of a royal pain to use.
And for us, double sinks is great for a number of reasons. We often use one sink to put dirty dishes for a while and still have the other sink to use. We let the dishes collect for up to a few hours and then clean the dishes once instead of almost continously doing dishes. My spouse and I are often cooking together and we each have a sink available to us. We just got this perk: we have preschooler twins who have decided they want to help us do dishes after meals (e.g. play with the water). With kitchen chairs, they each get a sink and they don't squabble.

But, we've had a number of times when a double sink has been invaluable to us.
