The downside of adjusting font sizes is that some application's GUI will look weird with large fonts. Well, then design better GUIs to accommodate both small and large fonts. Personally, I don't mind adjusting font sizes on screen with higher resolutions. Ctrl-plus and Ctrl-minus are easy enough for me in Firefox.
As the LCD and LED panel technology advances, the ppi number will just keep going higher and higher. I know IBM has already developed panels with 200 ppi for medical use, which cost $10000 each. I look forward to having one of those panels on my laptop one day. The screen will be so sharp that it should look like ink on paper.
