You've got the 24-200 range covered with just 2 lens. Sometimes it's just plain nice not having to worry about primes.
I'm looking to add either a 24-105 or the 24-70 in a year or two for my 5d3.
You're right! Sometimes, I miss having zooms... As much as I love and prefer fast primes, I think one day I'd like to add couple of nice zoom lenses for their convenience purposes.
