I have no idea as to the full range of options yet and I suspect there will be some people who that centre screen app draw style will work well for but that implementation IMO is inferior both to the normal Windows 10 start menu and Windows 7's. Windows 10's was starting to go a good direction though needed a lot of work and in theory, though lacking in practise, offered a good enhancement over 7.
I'm not sure that app draw style approach will work for me - I have pinned regular apps but also have other options brought in much more readily in both 7 and 10.
The thing with an OS is to enable the end user, give them options, everyone has a bit different ways in which things work the most fluidly and best - though there are limits having that app draw style, full screen options, etc. as options is a good thing, having 1 or maybe 2 fairly rigid approaches where at least 1 of them is a half-baked implementation at best really isn't a good thing.
