ahh, I was referring to both as I treat my tablet and phone as mobile devices. The Neo will be useful if you need two apps open and split between two screens. I work with two screens at work and I can see how that is useful on the go. Split screen on one screen is useful for recreational use, but not ideal for work, where dual screens is better.
the duo also looks interesting:
I question how many people
need to be able to see both apps at the same time on a portable device. I thought that it was telling that in the video you posted, the only shot of the device I could see in "twin screen" mode in which I could clearly make out what was going on on both screens, was showing an email app on one side and Spotify on the other! A nice gimmick, but probably less productive than working on a slightly larger screen and switching to Spotify when you need it. To be fair, I would quite like to have an app on one side and play a video on the other, but it would probably make me less productive.
I haven't tried to use a portable device in split screen mode since my Note 2, which I found of little use. I assume that technology has moved on since then, so would have thought that it would work just the same as the Microsoft device, just with a graphic in the middle of the screen instead of a physical hinge.
I have worked with two screens at a desk in the past and loved it. Maybe I'm out of touch in terms of how productive you can be on portable devices these days, but I've only ever viewed them as a way of achieving simple tasks (sending email, making notes) while on the move, or in a pinch frustrating yourself doing more demanding tasks in an emergency. For these situations, I think I'd prefer one larger screen (coupled with the existing facilities to switch apps) over two smaller ones, given that the majority of my focus will be on one app. I'm not saying that there are no situations when this would be a boon, just that they are the exception more than the rule.
