Content is not the be all and end all - the manner in which it is presented can far outweigh just the basic content.
I think people tend to confuse "content" with "data" or "information." in reality, "content" is the entire package. For example, two different chefs could write omelette cookbooks, and each might have recipes for a basic omelette nature, a cheese omelette, a Western omelette, an omelette aux fine herbes, and so forth. Much of the data (the basic recipe information) would be the same, but the content (the instructional text, the photos, etc.) would be very different.

Otherwise, you're asking for a dupe penalty.
Google addresses this in the "Separate Mobile URLs" section of:
In a nutshell: rel="canonical" is your friend.
