I've been searching all over for a computer or tablet with long battery life, and a tablet mode or detachable keyboard. I've been wanting to take notes and watch videos in portrait mode split screen while I'm out and about.

Firstly, not even the $800 iPad Pro can do split screen in portrait mode. I don't know why, but I'm not surprised it's something that Apple has overlooked.

So that leaves you with the option to either get a Surface Pro computer with an i5 or i7 processor with a maximum of 4 hours of battery with these Surface computers, OR you get something like a Samsung Galaxy Tab S9 which has an ARM processor and 11 hours of battery, but the problem is that these Galaxy Tab devices are wildly overpriced and OneUI isn't exactly my cup of tea.

Only Surface Pro 9 laptops with SQ3 exist, and these are also (shocking!) wildly overpriced. Of course, the 2023 Microsoft Surface Go 4 ARM model was scrapped in favor of an Intel processor, meaning battery life is out the door once again. Until battery life on these Surface computer is at minimum 6-7 hours I won't even look in their direction.

What gives? Is there any other computer or tablet I'm missing that exists? I don't want to spend much more than $800 or so on a device that I'd only use for specialized purposes; I'd buy refurbished but it's still completely insane to spend any more than that.
