I too had that feeling. Nevertheless at a point, you would even prefer the using the forum on your mobile phone rather than on your computer out of convivence. All you have to do is zoom in and out.
Is zooming in and zooming out not enough stress on its own? I use both mobile and desktop to browse through the forum, and I can boldly tell you that I enjoy browsing the forum on my desktop.
If you are using your mobile phone, there are some common mistakes you can easily make when navigating through the forum, like adding someone on ignore without realising it, quoting errors, and other common errors that you could have easily noticed and avoided by using the big screen to comment on the forum.
I think using both of them is actually good but I prefer to use my mobile phone to navigate the forum instead of my instead of using my desktop computer, why using mobile phone is necessary is because I can access the forum anywhere you find yourself because sometimes it could be that you not going be at home for some few days do to one time or another but with your phone would be able to access the forum this why using mobile phone is necessary.
