In the latex example, you need to change the document class to article, if 
you want 12pt fonts. To my eye, there is no difference between the two. 
But pdffonts tells me that latex is using LM Math Italic 8pt while ConTeXt 
is using LM Math Italic 9pt. This is not conclusive evidence since the 
fonts could be scaled.

In any case, if you want to change ConTeXt's defaults for 12pt, you can 
redefine the following

\unprotect
\definebodyfontenvironment
   [\!!twelvepoint]
   [        \s!text=\!!twelvepoint,
          \s!script=\!!ninepoint,
    \s!scriptscript=\!!sevenpoint,
               \c!x=\!!tenpoint,
              \c!xx=\!!eightpoint,
             \c!big=\!!fourteenpointfour,
           \c!small=\!!tenpoint]
\protect

This is just copied from font-ini.tex. You can use 12pt, 11pt etc rather 
than the predefined macros if you want.
