So I had the M1 12.9 IPP Late 2023 too early 2024. I noticed an issue with it. so I brought to a genius bar. They ran a test and said the logic board was going bad. It could die at any moment luckily 2 to 3 months later, Apple released the M4 13 Ipp and I was able to trade my M1 in to T-Mobile and get it and for the last year and three months I have been enjoying it to the fullest with the magic keyboard and the Apple Pencil Pro I unfortunately couldn’t wait, but I already knew the upgrades from the M1 to the M4 version or worth it tandem OLED better, keyboard, thinner body, lighter weight and with iPadOS 26 it has been amazing using the betas. I am in no rush to upgrade to the M 5 version. I understand the dual cameras on the front, but I don’t need it if it’s only a processor increase and a little bit more ram I like to hold onto my IPP for a few years before upgrading again
