Didn't mean to come across wrong.
Yeah - it was a PITA to run it all. The guy I bought the house from only had 2 phone drops in the whole house and 1 cable TV drop. As long as I was pulling cable, I just pulled 2 pcs of Cat6 and an RG6. Wasn't that much more money and certainly easier to do it all at once than skip one and then want it later.
My wife and I both work in the IT industry and my son is majoring in CS. Needless to say, there can be PC's pretty much anywhere in the house. Throw in his buddies bringing over their machines for LAN parties and it's not as much overkill as you might think it would be. Home PC, business, PC, my laptop, Wife's laptop, his PC, my daughter's PC, SlimServer machine, friends' PC's, XBox, and 1 (soon to be 2) Squeeze Boxes.
My main concern with the wireless was if it was degrading the performance of the SB. Sounds like the only issue may be the antenna. Haven't run into that issue so far that I can tell. My existing SB2 will do either but you just never know - and it's nice to be able to drag it over to other people's house where, as you suggested, it's not preferable to have to have it where the PC is.
