Hi, we've used iPhoto since it first came out, and moved to Aperture a couple years ago when iPhoto started bogging down from too many photos. We don't use any advanced Aperture features -- it's just used for storing photos and organizing them into albums. I'm curious, is the Photos app stable enough for mainstream use? Our photo library is a couple hundred GB in size; can it handle that ok? Is there any fear of losing photos from what is essentially a 1.0 product? Thanks for any input! Aperture has always been overkill for us and I'd like to move to something different, but I'm not sure if it's stable enough to trust with over a decade of photos.
