I see no reason ever to sacrifice quality for laziness.
Moments cannot be resurrected in post.
Interesting comment, but I find the opposite to be true more often. I love my primes and will shoot with them when I can control the flow of a photoshoot. However, there are situations where a zoom allows me to get more usable shots. If you miss a shot because you were changing lenses, or did not bring the right prime with you, that lost moment cannot be resurrected in post.
I haven't had my 24-105 very long. I bought a white box copy for around $700 last spring and I've been very impressed. I always shoot it wide open. I don't use a tripod too often, so the stabilization actually makes it sharper than my L lenses in actual use. I have noticed no chromatic aberration and I haven't used it for shooting buildings so I haven't noticed any distortion.
I'm taking it out today for a waterfall/fall foliage hike. Maybe I'll leave the tripod at home.
