I have a MacBook Air (2011). Great machine. But it sits and doesnt get used. I was thinking about selling it and going with an iPad 4. Everything I do can be done on iOS, so that leaves me with this dilemma. I have iPhoto running and always updating with pics from PhotoStream. If I l walk away from OSX, what would my alternatives be? Obviously all the pics I take on my iPhone would be saved on the device, but how could I back that up to save space and still be able to view them?
