I learned the lesson the hard way. Almost a year ago, I left my former employer, and I had to turn in my iPhone 4s. Being a computer professional, I knew the backup thing, so I backed up the photos to iTunes, both via iCloud and via iTunes to PC. But I forgot one more backup, to the iPhoto on my Mac. The backups on iCloud and iTunes are good, but I can not view the individual photos from there, and eventually I got a new iPhone 5s and got the backup iPhotos to my new iPhone this way. The first thing I did after I receiving my new iPhone is to restore the photos, and backup to iPhoto on my Mac.
I did one more thing, as I learned from my Nexus 4 experience, is turn on auto back up on google+. I paid $20 extra for the additional 10gb space on iCloud (for one year), when the time of renewal comes, I plan to cancel it, as now I will do backup via iPhoto, iTunes and google+.
Personally I felt the management of all these photos on iPhone/iPad is an interesting project. With Apple TV, I did see I play videos on iDevices more, and sometimes even slide show the photo. I did this quite a few times to my young daughter, when I found that’s more fun than the Netflix TV shows
