Okay, in desktops I get it.
An i3 is basically a pentium with hyperthreading. Then you move up to i5 which is a quad core, and an i7 is basically i5 with hyperthreading.

But what about in laptops.. all the i5s I've seen (except in 15" MacBook Pros) are 2 cores, 4 threads. What's the difference between it and an i3, then? Is it just so people who haven't done their research just see the name of the processor and assume it's better?

Also in laptops i7s are 2 cores w/ 4 threads aswell.. what's the difference between all of these?

As indicated in my guide (if you read it):

In laptops, quad-core models will have Q suffix added before M. IE) i7-2360QM. This includes XM models (the extreme edition moniker). All other models are dual-core.

i5 in laptops have HyperThreading (like i3), but has Turbo Core function (i3 do not). i7 without Q suffix is basically i5 with a slightly bigger L3 cache, with varying clock differences depending on what model it is (some are low-voltage, some don't have iGPU, etc).
