For me, I browse the web differently on desktop, for example on desktop if I visit HN, I might open 5 different links and their comments at once before visiting them one by one. In the middle of that I might open email, and then open tabs from the email. I could easily end up with several windows with 6-7 tabs in each open. That sort of thing I would never do on my phone or tablet, just because of the form factor I k…
I'm currently using an iPhone 5, have 11 tabs open and am streaming music from spotify. Other than occasional crashes and a tiny bit of lag, my aged phone handles it very well. On the other hand, when I'm on the desktop I open multiple browser instances with 20+ tabs open on each of them. I guess I have a problem :).
yes, its (at least on android) just swiping twice (once from the top to open the window view and then to the side to close it), but even that takes more effort than just mouse-wheel clicking on the tab.
After that tab is closed, the browser needs to rebuild the new/old tab. thats even more time you wouldn't have on the desktop.
everything just takes a little longer on the highly performance optimized phone, and it adds up to stop - at least me - from just going into the comments threads. especially because actually opening takes even longer, as you'd have to long press on the link to get that option.
now, with this device you'd be able to actually click/close tabs as fast as on your general desktop. Suddenly, the device is no longer constrained by the slow inputs that the user is giving. And now, the phone will actually need to perform that much better with the same amount of resources. I haven't used the DeX and don't know wherever its able to handle that, but thats (i think) the thing most people hearing about it are worried about.
