I've got about the same gear as you, and I started out shooting only jpg because I didn't want to spend the money for a RAW post-processor. Liked others have said, T2i shoots excellent jpg in auto and modes.
I do PP the jpgs with free FastStone, but it only takes about 30 seconds/photo, not 10 minutes. After I figure out the PP settings for the 1st image, the others within the same lighting scenario get the same PP - just a few clicks per photo.
That being said, I recently bought a P&S (SX150) as a casual carry-around... and it also takes good jpg in both auto and modes.
To all: Yes, I know that RAW would give me "superb" IQ instead of just "excellent" IQ ... to each his own.
