Some questions to ask yourself before you decide:
Are you sure you never have humidity variances in your humidors? The cello, though porous is a small amount of protection from swings in humidity. I have also seen an experiment where someone used high humidity and one of each to see how mold would attack them. The unprotected was trashed, the celloed one just needed to be dry boxed.
Do you herf/travel/move your cigars much? The more they get jostled, the more the cello can do it's job.
Do you trade/bomb/send many cigars? Same as above. Cello is just a little bit more protection. Leave them on, or stock up on singles baggies.
How long before you will smoke through a box of cigars? I agree that removal can help with aging. But cigars can also age TOO much and become bland. How soon you intend to get to said cigars should help make the decision. Wstakelin had the right idea, remove some to get them aged quicker for smoking and leave on those that may set for a few years. I have over a thousand sticks and many may last ten years.
How strong of cigars do you own? 71RIG had a good point(as well as a humorous one
). Stronger cigars can withstand quicker aging and may meld their flavors together without loss of flavor, while milder cigars like many Dominican and conny wrappered sticks may age themselves to blah in a hurry.
My feeling is instead of a black or white answer, some shade of gray may work for you personally.
Though what do I know, I have never even stayed in a Holiday Inn express.
