A lot of current laptop designs are leaving free space around the battery so more AI can be poured in at a later date, through a dedicated nipple presumably.
The no gain part I'll argue against. Having two browser windows open and getting to see both would be really nice a ton of times. Or one browser and a document/pdf whatever.
Like having a Netflix show running up top while doing work on the bottom half. Or writing a paper while having reference material open and visible. Or simply just reading an article without having to scroll as often.
Usage wise, a tall screen would have tons of usage. I just wouldn't pay an extra $2,000+ for the privilage of it. I'd definitely pay like an extra 20% or so to have it, though.
I had thought when I posted that to put 'no justifiable gain' but did not for some reason, maybe it ruined the flow but with hindsight and as you and others have explained perhaps it should be there.
I do think it is a bit gimmicky and the problem it seeks to address could be more practically solved in other more conventional ways, but it is an attempt and a first iteration and has merit for that and who knows where it will end up, maybe all our screens will expand and contract like the windows within them one day.
I wouldn't say no gain. I would love that real estate on my bedside stand I use with physical disability. I would not want the sub 17" form factor and keyboard though. I struggle to do anything super technical without a second screen which is a pain in the ass. I can't sit at a desktop and the ergonomics of a laptop are unbeatable in my situation.
It looks like when it's extended it adds a second screen. But it's vertical, one on top of the other. I feel like doing it horizontally would be more natural to use. Baby steps, I guess.
I have a monitor on a custom made arm that sits above my laptop when I need a second screen.
It works well in a tight space like in a board meeting at a conference table or plane seat. Vertical doesn't make a real difference in my experience. You just need two spaces that do not move so that you can quickly reference multiple documents and keep your place between them.
Two or more windows on top of each other. Have you never even put a monitor on its side to get more vertical space?
As a Dev that needs some communication with a team, documentation and potentially a video for entertainment whilst working. Monitors that are taller are great. The LG dual up is my holy grail right now.
