wroot How is Planner overkill? Literally looks the same as To Do and has the exact same views as To Do with the list view. If My Day is incorporated into Planner (and a personal Planner Board) it would then be the exact same with the option of other added capability, not that you necessarily need it but for a lot of people they probably would, e.g. myself. It's not like that other capability makes the functionality of To Do difficult to find. Please explain what would in planner makes you not want to use it over To Do.
For OneNote vs Loops please explain what the functional differences are. OneNote and loop both have live collaboration. Both can showcase written information, images, tasks and links on single pages, with the same idea of sections (or workspaces) and pages. If they incorporate ink into Loop Workspaces then again there is no difference between the apps. Please explain what differences they have that means Loop shouldn't be a replacement for OneNote, because as I see it the talk of one being for live collaboration and the other not so means absolutely nothing without explaining why Loops cant be used in the same way as OneNote can. Loops then has the added benefit of allowing Loop components if required by the use case.
The mention of OneNote being used by millions in various ways does not negate what I just mentioned at all unless you can show any use case that cannot be done in Loop workspaces/pages. Please, please send some through as all I am currently seeing is marketing talk that does not actually provide any real information on the topic.
