I thought this might be a useful read to .com.mx/.mx domainers:
(Source :
NIC México - Noticias )
Percentage distribution of all types of .mx domains as of July 2011:
Domain Type - Percentage
. Com.mx - 68.32%
. Gob.mx - 1.22%
. Net.mx - 0.08%
. Edu.mx - 1.53%
. Org.mx - 3.28%
. Mx - 25.56%
TOTAL - 100.00%
So at the moment there are 3 times more .com.mx domains than .mx. It will be interesting to see how these percentages will vary in a year or so.
