I don't have a laptop or a smart phone. I also don't go to the library to use their computers or anything. If I had a tablet or laptop, I probably would browse the site in public. I would love it if I could take a laptop to work and work on reviews during my lunch break.
The only time I'm on my laptop in public is if I go out to grab lunch or coffee and still want to work. There have been a couple times where I've tried to go on EF and found the site blocked by whatever network I was on at the time, which is always disappointing.
In public, I'm constantly on my phone and on EF just browsing. It is a great outlet for being bored and in public, like waiting in line at the grocery store, to waiting for a doctors appointment. It is nice to have EF on my phone. I don't mind at all.
I was seriously just going to ask the same question!
I'm currently sitting in my car in Starbucks/McDonald's joint parking lot borrowing Starbucks internet while I wait to pick hubby up from work. So, yeah, I definitely browse the forums in public. I need to be at least semi-private to shop the toy pages though.
I browse on my smart phone occasionally, I don't take my laptop with me often, but I did look at EF when I was stranded at the airport for 8+ hours. I just tried to situate myself so the screen was facing a corner so people couldn't really see.
