Con Pointless to use this for legibility unless you're on an exceptionally small screen device
The tiny point size does not scale well. It's designed for a singular purpose and does well for that, but unless you're working around those limitations the poor readability will slow down your work.
Con Not as pretty as other fonts
Other options look better than Tiny Font at bigger sizes.
