I've not yet moved to iCloud, although I just updated my oldest MBP to Lion last week in preparation. My concern is that I live in a rural area where my only internet access is through AT&T data connect cards. We have two at the maximum they allow of 5GB per month, but we are always going over and experiencing rather large bills because I work from home and send and receive large files on a regular basis. When I move to iCloud how or will it affect my data use on my computers? I'm not worried about my iPhone as much since I never use the wifi at home. Thanks in advance for any helpful advice. I've studied the Forums and the iCloud literature but haven't really found any specific answers.
