I'm still not getting how the 7D was lacking and the T2i is better
Well, clearly the 7D just isn't cool. Consider...7D...T2i. A number and a letter vs. a letter and a number with an 'i'. Think iPhone, iPad, iMac, iPod...and not just Apple - an iRobot vacuums my house for me, iSpy was an awesome TV show (who doesn't like Robert Culp, and yes I took a contractional liberty there), but you get my point. Without the i, the 7D is just...lacking.
