You can't really compare FoxTeach to DevCon. DevCon is the MS sponsored event. It is much bigger than FoxTeach. (FT=300 attendees, DevCon somewhere in the 4-digits...).

FoxTeach is a two day event (at elast it was this year), while DevCon is normally 3 days, and this year even 4.

However, FoxTeach was a great event. Much cheaper too than DevCon.

So the bottom line is that both events are great conferences but hard to compare.
