Many people here have various Apple products. I have an iPod Touch and now I'm getting an iPad and probably a desktop Mac pretty soon. Since, I'll have more than one device, I'm getting a little concerned about synchronization and backup. I'm looking into Mobile Me, but it's subscription based, so I don't know if it's worth the $99/per year as opposed to using a desktop and a hard drive back up with Time Machine. Does anyone use Mobile Me, Time Machine or both?
