I'm hoping to switch to Mac shortly. I realize that I will need to "think" a bit differently when using OSX than in Windows. It's not just a matter of what replaces what. I'm working on this process, but some things still leave me a bit confused. In OSX, it seems that many things are stored in libraries or databases, instead of folders. Examples... iPhoto, Aperture, DEVONthink, etc. This is all cool and I can see the many advantages to that approach, particularly when it comes to searching for photos or documents. However, in this world where the "cloud" is so dominant and we share everything everywhere, I'm not sure how this fits in. With iPhoto/Aperture library files or DEVONthink databases, how do you have your photos, documents, etc. in the cloud so you can access them from other computers or devices? Does this mean you have to have duplicates of every file and have them stored and maintained in multiple different formats? How does Mac software fit with the new cloud architecture?
