I don’t use an external display so I can’t comment on that. But, overall this is as seamless as ios 18 was on my M4. No lagging, in fact it is much faster in most responses than ever. If your main concern is using it with an external display then you might need additional feedback before deciding. But if that’s not your primary concern you should have no issues. However, all experiences will depend on the specific user, and what apps are being used. I use this ipad all day long, very rarely use my mac anymore, and I’ve been extremely pleased.
