Call me silly, but I haven't the foggiest how the cloud works. Than said, let me provide my concern. I recently upgraded from a 64GB iPad 1st Gen to an iPad2 16GB. With apps, photos, etc, I have about 4.5 GB of storage left. If I use the Cloud on my iMac, does all the stuff I put on the Cloud transfer to the iPad and use storage space? Or does it wok similar to DropBox? I know y'all are shaking your heads thinking I shouldn't own anything techie! Thanks for helping.
