Quick question - Should I spend the money to upgrade to Lion just for iCloud? What benefits will iCloud bring me? I currently have a Gmail that has all my contacts, calendar, google docs and emails sorted and paired up with all other employees' gmails from my company. I don't plan on transitioning any of those features to iCloud, so what benefits does it bring me to upgrade? Photostream is the only thing I can think of.. am I right on this?
