JJ at Orange Wedding Films has another video, this one checking on overheating of the T2i. There have been some overheating issues with the 7D when continuously shooting for over 20 minutes, and JJ checks to see if the same issues arise in the T2i:

I think this isn't that big of a deal in the indie film community, but anyone shooting live events needs to be aware of it. With the battery life, and the limit on continuous takes, the Rebel doesn't really meet the needs of the live event shooter, IMHO.
