Here's what I can tell you.
1. Outside of torrents, you're not going to get the full benefit of that gig for most applications.
2. Netflix is awesome with it. Load times of a few seconds for high def.
3. Hard wire anything that doesn't move often (TV/Blu Ray/PS3/Desktop/etc) and have plenty of ports around the house you can plug your laptop in just in case you feel you need more speed.
4. Use wireless the rest of the time. You seriously just won't notice that big of a difference web browsing unless you have serious interference issues although if you're gaming, you'll want to use the hard wire.
Honestly with current web applications, a gig is just about overkill. Sure that might change in the future once gig becomes more prevalent, but it's seriously overpowered for pretty much everything currently. Short of having multiple people streaming HD video and downloading/uploading via torrents, your pipe is going to be bored most of the time.
First of all, WiFi operates on UNREGULATED
This is completely and patently false. There ARE regulations on wifi. They are merely moved into the unlicensed spectrum which is NOT the same thing as unregulated. Granted, the regulations are pretty few, they are NOT non-existent.
After something like 20 years I finally found a system that won't run Debian unstable right now. My Panasonic Toughpad FZ-G1 magnesium tablet + iKey Jumpseat magnesium keyboard. Systemd and GDM break. Bought (for less than full price) because I am a frequent traveler and speaker and really do need something you can drop from 6 feet and pour coffee over have it keep working.
But because of this bug I have ubuntu at the moment, and am not having fun and am eager to return to Debian.
