Some people are just really lazy. I managed to crack my friends wep password in around 5 minutes (Story details are on page 1 of this thread somewhere). I'm no hacker or anything but it was actually really easy to do it. First you scan for networks with aircrack-ng, when you find your network you target it using its channel and mac address, then start injecting packets and eventually you will get enough data to crack it. It doesn't take very long, require much knowledge OR much cpu power.

I did it on my netbook which is only 1.6ghz. Seriously if anyone here has a WEP password you should REALLY consider to change it to a WPA.

Intel i7 4770k 3.50ghz, 32gb Corsair Vengeance RAM (8x4 kit), 2 x 2TB WD Black HHD, nVidia 770GTX 4gb OC, Asus Z87-A Motherboard, running Windows 7 64 bit.

On the deal of why people don't change from WEP. Some people may not know which is more secure, so they just pick one. Until just now I never really looked into which was more secure. I'm pretty sure mine is WPA, but I haven't looked at my router settings in awhile, and I forgot my username and password for it.

Your setup might sound secure to you but there are some smart people out there
Spoofing a MAC address only is really feasible if you know a MAC address thats on the whitelist already. If you want to brute-force it... I imagine that would take some time.

Of course since MAC addresses are given out in blocks to device manufactures you could narrow down a brute-force search a bit. Ie someone allowed on the network has an iphone, so you already know the first 4-6 digits of a whitelisted MAC address, which leaves 6-8 others... around 16^6 possibilities at the best case.
It can be done, of course, but someone would have to be very dedicated.
