1. iPadOS is kind of ass. Multi-tasking is lacking, cursor support is ehhh, and applications are still dumbed-down. This means more clicks, more actions, to do the same thing.
2. Bluetooth is ass, trust me I know. Thing will disconnect and you will need to manually reconnect them. I don't know why in the year 2025 bluetooth isn't completely seamless, but it isn't.
3. Rinky-dink keyboard and real keyboard is night and day. I've used those iPad keyboards. They suck.
2. Bluetooth works fine. I haven’t ever needed to re-pair my Bluetooth keyboard to my Mac or iPad
3. The iPad works with any random Bluetooth keyboard and mouse. Bluetooth keyboard support has been available on the iPad since 2010. Bluetooth mouse support has been available for 7 years+.
If you have problems with Bluetooth keyboards, that says more about other operating systems. I’ve used them since my G4 Mac Mini in 2006.
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.
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.
