Two of my Macs are still using "spinning rust" 
For most stuff there isn't a huge amount of difference in terms of speed, usually if you open something you don't use often it gets a bit laggy compared to MacOS on an SSD. Windows is another story though. It starts ok but after a few weeks everything gets so sloooooooooow.
I think MacOS is just about acceptable running on a hard disk, but I am looking at SSD options for my 27" iMac. I can get 1TB Crucial SSD for about £60, but I think I could maybe get one a little cheaper if I keep on looking.
On the Mac when you launch an app it's icon bounces in the dock until it opens. On my SSD MacBook the icon has launched before the icon returns to the ground. On my other Macs it bounces 2-3 times. But we are talking a few seconds so it's no hardship. But you kinda noticed it after you've been spoilt by an SSD!
