You can increase the font size in the settings
Text isn't everything, though. Doesn't it also make icons smaller, buttons and other widgets harder to aim for, and everything generally harder to see?

I've set the dpi to around 600 and it's been ok. the accuracy of the touchscreen is pretty good so i've not found any problems aiming for things. Sure, i've probably halfed the years of good eye sight I have left but it's better to burn brighter etc etc
I do believe I have "landed" on a setting of dpi=550. It moves the "back", "desktop" and "stop/splitscreen" buttons to the side of the screen again. (I really don't see any advantage of having them at the bottom of the screen, unless you want them "out of the way": Anything requiring use of the bottom of the screen is awkward because of the keyboard...) It is also the highest setting that allows "Agenda" to work properly. (You can make NEW appointments, and copy/paste existing ones, but you cant edit existing ones with higher setting...) And it still gives me proper "desktop-version" of some sites that didn't on my previous setting of 530.
