I had this choice to make last month, I went with Cat5E wiring.

* It's cheaper
* It's faster 100Mb/s (what's the fastest wireless?)
* It's not that hard to run cabling.
* It's more secure from prying eyes.

I live in a two story house (I own it, so no landlord issues). It has an unfinished cellar and an unfinished attic. There's a sewer gas pipe that runs from the cellar through the attic. I can pass all of the low voltage wiring I want through the "chase" that the pipe runs in.
