I have a surge protector on my computer. It's a nice one. Not the top of the line but not super cheap either. I think it came with a warranty in case it fails. Not that I kept any paperwork involving such a thing.
It has eight outlets on it. Five are side by side and two are actually off to the side. It also has protection for coaxial cable and phone line, and a cable management system and other doo-dads but I'm not going to explore them right now.
The problem with such a set up on a surge protector is that most electronic devices now have an electronic box of some type attached to the end of their plug. Therefore instead of a nice normal little plug they have this monstrosity of a box. With that box the plug will then block several outlets. My cell phone charger has a narrow box that would actually only block one slot if the outlets were horizontal instead of vertical. Instead the bloc physically covers two outlets and the cord interferes with a third outlet. My router has a monstrosity of a square box that can block the outlets on either side and from top to bottom. However, my printer has a nice box that is actually in the middle of the cord so that the box will sit on the floor and it has a normal plug to fit in the surge protector.
Thus, with all of my computer equipment, I now need to purchase a second surge protector to protect everything. Currently, my speakers and my cell phone charger are plugged in with no protection. I wish that these companies would make smarter equipment and start adding a "normal" plug to everything.
