Back-ups are a PITA, but are pretty vital. And I'm betting that about 5% of Windows users, and 10% of Mac users (thanks Time Machine) have any back-up at all. $1000 for a DSLR, $2000 for the lenses, $5000 for the holidays. Losing all your photos because you didn't back up .... priceless. There are online services. Mozy, Carbonite, Jungle Disk, rsyncx with a cheap web host, perl scripts mirroring your data to the server in your friend's basement ... but it's just not Mac-like to have so much choice. There should be a default option, and I'm sure Apple would love to control it. Apple is building a datacenter. A big one. What's the bet that they could offer 200GB backups for $200 / year (let's just assume they charge a premium - $100 for unlimited is more competitive), and sell it through the Lion App store? They'll have the servers. They'll have the captive audience. They'll have one-click purchases set up, so people don't procrastinate while they consider their options. There would also be some scope to integrate it with MobileMe. If they already host the photos, it's a no-brainer to make serve them to the public. There's lots of cloud things they could do here - iPad, MBA, iPhone, iMac - all connected to a central repository. Time Machine (as it stands) is OK, but it's not ideal. It can easily be stolen or destroyed along with your computer in a real catastrophe. And you can't take it everywhere you go. What do you guys think? And how could they market this? I can just imagine the ad ... "Hey PC, can I see your baby photos?"
