I've used an iPhone. I know, for me, bluetooth does not work fine. It drops somewhat frequently.

As for keyboards and mice, sure, they work, but what's the point? If we have to attach a keyboard to an iPad and carry it around as it's own thing, then a laptop is more convenient. It has a keyboard, mouse, and screen all built in one thing. No bluetooth required, no charging required.

Are we talking about Bluetooth headsets now? I thought we were talking about keyboards and mice.

So what crappy Bluetooth headphones are you using? I haven’t had any issues with either my AirPods Pro or my cheap $60 Beats Flex.

And you can go months without recharging a keyboard or mouse. The advantage of the iPad is I don’t need a keyboard or mouse all of the time - well my wife doesn’t. It has built in cellular which is unlimited via T-mobile and when I go on an airplane, I can leave my keyboard and mouse in my bag.

And honestly, I hate working on just my laptop for any period of time and I still take my Roost laptop stand and a keyboard and mouse with me and I have an external USB powered/USB video external monitor I take with me and sometimes use my iPad as a third monitor for my laptop.
