Even if you are giving something up for cordless--and I'm happy to stipulate you may be to some degree, there are a lot of situations where you want to do a quick touchup, clean up a spill, etc. and a cordless vacuum like a Dyson is so much quicker and easier. It's the same with a lot of battery-powered tools. They may not be quite as powerful as a corded or gasoline version but they're increasingly powerful enough, especially for relatively light duty use, and they're a lot more convenient.

Is there a vacuum that doesn't have a battery but uses the same form factor? I don't mind plugging it in but I don't want to drag around another object I just want to use it like a swiffer.
