percentage of players using software

Hi all,

first post for me. Just downloaded Poker Tracker after 6 months or so of playing NL cash games around the $1/$2 or $2/$4 range.

Just wondering if anyone has a view as to how many players out there are already using software of some kind - is it starting to get statistically significant?

Given the edge that it should bring, do people think there's only a limited time to 'cash-in' before either the poker sites stop data mining somehow, or Joe Average catches on?
