Contacts can be organized into groups on the iPhone or iPad to make them easier to find. However, it may not immediately be obvious that this is possible because Apple still doesn't allow you to create those groups on iOS 7 -- you can only view them. To create groups, you must do it in iCloud or from your computer. Here's how to create groups using both methods:
Jim's having trouble with PhotoStream on his Desktop. It works fine on his mobile devices, though. Leo wonders if Jim turned it off on his Desktop by mistake. This is not unusual for Apple to have problems with their online service. He recommends enabling it through iCloud. He should also turn it off and turn it on again on all devices.
Rick entered a date on his calendar on the iPhone via FantastiCal, and his friend noticed that it appears on his calendar as well. Leo says it will do that if he had set it up that way. The calendar will see that he's put a name in the event and email it as an invitation. It's a nice feature, but scary if he doesn't see it coming.
Mark has two thumbdrives hooked into a PogoPlug connected to his MacBook Air, but now his drives are read only. Leo says that drives can end up read-only when they're damaged. If he removed the thumbdrive without ejecting it, it could have damaged it. Leo says he can pull the data off it and then reformat the thumbdrive.
Scott just got a new iPhone 5 and found out he can't use it without iTunes 11 -- he would have to update his OS as well! Leo says that's true, but Apple handles sync over the air now, so he doesn't really have to sync directly. He can use iCloud and iTunes Match, if he's a subscriber of it, to sync his music. He can also sync via Google Services.
Dale has a new iMac, iPhone 4S and an iPad for photography and decided to sync it all together with iCloud. When he synced everything though, iCloud shredded the address book in Outlook on his Windows computer. Leo says that's not surprising. Syncing can cause issues like this the first time around, that's why it's vital to backup his address book before trying something new. Syncing multiple address books in different formats (PC and Mac) really can be problematic. iCloud is a mess anyway.

No, but he needs to go into iCloud from OS X system preferences and enable it. Older PowerPC macs such as the G5's probably won't be able to take advantage of Back to My Mac though because they can't access iCloud.
Apple wants everyone to be using Lion, and soon they'll want users to be on Mountain Lion. Leo says he'll probably want to upgrade to Lion because the only service that iCloud works with in Snow Leopard is Mail. He won't get some of the other features without going through quite an elaborate process. There is an article from EggFreckles.net that will help him use iCloud in Snow Leopard if he still wants to.
