This is exactly it. I of course have a web browser on my laptop. If I'm running errand, going to the grocery store, or going for a walk, I have never had a need for it other than wanting to satisfy some random curiosity. Not having a web browser on my phone for the last 4-5 months, I haven't run into any issues. If I'm simply bored, I have koreader installed which is synced to my ereader at home. If I do have that random curiosity pop up, I'll take a note and research it later.
