Not sure if anyone here is interested in sharing their approaches or not but I could use a bit of help here as I am new to mac, ipad, and apple in general. I have two iMacs, one macbook, and one iPad and they are used between my wife and myself. Basically, one iMac each, and one user account each on the macbook. We keep all of our files on our iMacs, then keep them backed up regularly. Anything on the laptop is either a copy from our computers, or something we downloaded which isnt important enough to store on our computer. Where I am getting a little bit confused is how to handle iPad, use of the new iCloud, and how many apple id's we need to create. Right now we have just one apple id, my own, which has been ok up till now for purchases but i think will begin to get troublesome soon. Right now I would like to purchase OSX Lion on the app store, but can I purchase it only once on my apple id? Otherwise how do I install it on both iMacs? As well, if I set up iCloud to send everything to my computers, will it only do it to the apple id set up on the iPad? Anyway, are there any others out there with a similar family setup who are trying to work through the best approach or who have already done so and can share their tips/experience? Any help is appreciated!
