A bit of background: I am nearly finished uploading my CDs to my IMac, and am now wondering whether to go over to the Cloud. I was previously planning to download (sync via Mobile ME) the music on the IMac to my 64 GB IPad and use the IPad with the audio system in the living room, with my IMac upstairs. I will soon see if they all fit. If not, then I will have to selectively sync. OR..... Is this what the Cloud is supposed to be for? I have been reading that once you go to the cloud you no longer need to (no longer CAN?) sync the old mobile.me way, and that stuff is in the cloud. Or, at least the stuff that cannot fit. But I have been reading people's comments about stuff not working. I understand ITunes Match (that you pay for) will make up the difference if you have more stuff than will fit. Actually, this is what I am not sure of. Does stuff actually stay on your Mac? I would prefer not to have stuff actually leave my Mac and go to the cloud. Unlike many, I do not travel. I do not need to have music when I travel. I just want to have my Imac collection on my Ipad and hopefully not have everything in the Cloud. I have me.com but hardly ever use the address (just a few emails forwarded to me at another address.) I do have lots of photos, but in Iphoto 11 I am not sure how you find out how much space the library takes up. I seem to have 26 GB of music files,though. And it seems that only 5GB of music is free in Icoud before having to purchase more space. I am probably misunderstanding a lot. Has anyone actually updated and experienced how Itunes selections are affected both on your Mac and a device like the IPhone or Ipad? Thank you!
