I just got back from 4 weeks traveling. I took an iPhone and an iPad, but didn't take my laptop and for the whole time completely ignored the world of web development.
- Didn't visit GitHub
- Didn't read any dev blog posts
- Looked at Twitter once or twice for about 30 seconds (and realised if I wasn't in this industry I probably wouldn't use it at all)
- Deleted pretty much every email I received without reading it.
I still used the internet though.
I pulled out my phone whenever I needed directions, opening hours or prices. I did some banking & flight booking. I checked train timetables. Occasionally I posted an update to Facebook or a photo to Instagram. I read the odd news article.
