So your not wanting to talk about continuity this is just a chat about IMessage's again
as it seems your only counter argument
If you want to start on your phone and continue on your laptop it's a simple fact IOS is limited to a few apps, but does it very well
It does not matter how good Imessages is or is not its one app out of many users use for productivity/communications etc, you are stuck with one app only,
If your definition of better is Apples Hobson's choice then stick with it IMO
FYI I also provided a native sms/mms app along with other messaging platforms as it was in context but I could of easily shown many native apps
I think this chat is now derailed from its intent and going nowhere
The funny thing is my examples were all grabbed from my MBP16M2 because I can have access to all my Fold 4 apps and my IP14P continuity on the same laptop LOL So I am very aware of IOS good but limited continuity productivity
