I haven't had any crashes, and it's good to see that iPhoto still works as migration between apps has been problematic for me regarding organization. For those with issues or complaints about the Photos app, voice your concerns by emailing Apple and letting them know what you want changed. They might not change things, but the age old saying applies here as well - The Squeaky Wheel Gets The Grease. I know I'll be writing them an email.
