I have a Mac Pro that is still running Snow Leopard (because of software incompatibility issues) and thus nor compatible with iCloud, a MacBook Air running Lion, and an iPhone 4s. I sync the iPhone to the Mac Pro (my main Mac) in the traditional way. I will now be getting an iPad and I wonder if I should sync and back it up to my Mac Pro also, or if I should go the iCloud way. Are there any advantages or disadvantages either way?
