I could not agree with you more. However, there is a way to increase/decrease font size:
To INCREASE text size: Ctrl+Shift+>
To DECREASE text size: Ctrl+Shift+<
Refer to: http://windows.microsoft.com/en-US/windows7/Using-Sticky-Notes?SignedIn=1
Also:
"With some modifications with that font, you can use other fonts as to change the default font in the Sticky Note.
1 Start
2 Run - type regedit
3 Navigate to: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts
4 on right pane Find "Segoe Print (TrueType)" and "Segoe Print Bold (TrueType)" - double click (don't forget to change both - one by one)
optional - you can delete other Segoe fonts - select(one click), press Del, press Yes
5 Change the value(double click on font) to the file name of any other font that you wish to use that is already installed - for "times new roman" it should be times.ttf .
6 Restart the computer. "
