Virtual desktops are useful, but often a physical screen is better. For example, it's much more convenient to glance to and fro from code and logs/stack trace.
This is why cursors on text terminals would blink.
But I'm not sure making a mouse pointer blink is the right thing to do.
The whole Windows-Icons-Mouse-Pointer environment was developed when 640x400 was a high resolution and 22" monitors were considered huge. So easy to pick out the pointer at rest, but I can see how you can get lost on basically a 4K resolution TV.
