I've been wondering this as well. I love the current collection at ACNE, and noticed that a lot of their jeans and trousers are cut as ankle-grazers (rather like the All Saints short-kicks) but fashioned to sit above the ankle without a roll. The clean lines are almost envious.
I've stopped wearing my short-kicks because of the slight drop crotch (can a tailor fix it?), however if I wear them high above my belly-button they look like the jeans ACNE are sporting this season.
The problem for me is that when it comes to jeans I think a roll looks sexy. I've worn my jeans for years with a roll or two, way before it really became a fashion staple, and I can't see myself stopping for a while.
With trousers/chinos, however, I think the cropped look is awesome.
There is one major drawback, though. If, or when, this style goes out of fashion, you will be left with a pair of trousers the fashion-world deems unfashionable. In ten years time we might scoff cropped trousers as being ridiculous: effectively they look as though you're wearing a pair of trousers too short for you.
Consequently, maybe you should try this with a pair of trousers in a less versatile colour? If this colour goes out of fashion, you may discontinue wearing the trousers, however if you were to crop a pair of extremely versatile trousers and the look went out of fashion, you may have ruined a pair of awesome trousers. At least a roll is reversible.
There's two other thing you can consider: having your trousers lined with a contrast colour, or taken up to produce a hem.
With the latter, look at the following picture. Notice that the trousers appear to be cut above the ankle, but could perhaps be let down to produce a standard leg length (which could then be rolled if you decided you prefer this look)

Or, regarding the lining idea, check out these beauties from Mr Porter (Jill Sander's):
The contrast lining, IMHO, adds an incredibly quirky touch to the trousers which I think is extremely Italian.
At the end of the day though, it really does boil down to personal preference. I think one or two cropped trousers, which fit perfectly, would be extremely enviable this summer.
