Hi all, just have a couple of questions before I subscribe for iTunes Match: 1) How much data can I expect the service to use each month? I currently have a 2 GB / month plan, and typically use about 1-1.5 GB per month. I listen to music while driving and walking on campus. Will data usage be the MB size of each song file streamed? If so I feel like that'd add up very fast.. 2) Will my music files still be stores locally on my computer and on iTunes? I have a lot of time on my computer where I cannot connect to wifi and would like to listen to music on my computer. Thanks in advance if you can help me out!
