With the new iCloud everything seems to have gotten so much easier, you can sync your documents and apps on the go, however furthermore Apple has just announced Photo Stream, which will sync the camera roll on your iPhone or iPad to the cloud, then keep your other devices updated, including your Macs, using iPhoto or even a PC where your photos and videos will show up in the pictures folder.
Your last 1,000 pictures will be stored in the cloud, but only for 30 days. Apple doesn’t intend to replace all your local storage, but instead, provide a robust syncing service.
So take a photo on your phone. In an instant it is on your iPad, in your iPhoto library and available for big screen display on your Apple TV connected set. Go on vacation, and your pictures will be home before you are. Apple is talking about WiFi, so no word on if the service works over 3G, but we will keep you posted!
