I agree with erich1010@yahoo.com, today its not really anything abnormal at all. It is the time we live in -- "tech" is definitely "hip" today.
This is going to sound extremely sexist on one hand, but its the truth...
You know how you can easily tell tech is in now? Look at all the women online today (ok ladies don't throw knives at me yet...lol)...back in the day the VAST majority of the "online world" was by far dominated by males. Sure there have (and always will be) exceptions where here and then you'd "run into" a female on a BBS or chat room...today even the type of woman who 10 years ago would of said "that is way too lame" at the thought of using computers and the 'net, wholly embrace the technology and they now think its "cool" just like what us "geeks" were trying to say 10, 15 even 20 years ago.
Everyone has DVD players, more than one tv (more and more getting HDTV sets), MP3 players (you can have my Ipod when you pry it from my cold dead hands), cell phones (seriously besides countries that can't feed themselves, who DOES NOT have a cell phone today), hell even internet dating is more "accepted" in society than ever before...
So definitely NO...home networks or technology in general is not unusual, geeky or the like in today's world.
Now in my case my gf makes fun of me for how obsessed I am with maintaining my "geek toys"..but that's another story..;)
