Is it really? I tried one of the USB microscopes with a screen, and the lack of depth perception was a massive hindrance when soldering. I solved it with a pair of jeweller's loupes:
I'm an EE in my 40s, have 20/20 vision, and never solder without a microscope no matter how large the packages are. The ergonomic advantages are worth it.
I really only learned to appreciate how useful this is when debugging a PCI express extender cable and seeing the tiniest little solder ball shorting out two wires adjacent to each other.
