I'm not sure that's quite the true distinction between a hub and a switch. Hub uses broadcasting, so it affects all devices on the hub, while a switch uses MAC addresses to connect devices. Both decies share a backplane and if your backplane cant support the number of devices then you have a different issue (blocking). A switch is able to transfer data between two devices directly, while a hub will impact everyone on the hub. It's not that a hub only has 100 megs to share with everyone.
I tend to think of a switch as a smart hub. It knows who wants to talk to whom, but even a switch shares a backplane and can suffer from blocking. ie a 16 port switch, if all 16 ports were doing 100 megs at full duplex, that would require a 3.2 meg backplane, but most switches are not non-blocking.
That's what I understood... but yes, a switch is better.
