I put once a day. When I'm at home I usually spend a lot of time on the internet between checking news, checking forums, reading blogs, writing and posting on my blog, playing World of Warcraft, etc.
When I was out of town recently I didn't do a lot of internet. I downloaded a couple of Kindle books (already owned just needed to download to the device I was using). I used internet on my phone to get directions. I used internet to check the weather (there was a lot of flooding going on at the time). I used internet to get email and to do a few text messages. It wasn't a lot, but it was nice to have.
To me, internet is pretty much like having any other utility service. I expect it to be there when I want to use it.
