regarding point1, have you seen Arcadia?WISHlist....sure.
1. A resurrected Dungeon magazine, with 3-4 different power level adventures I can if into any campaign world. Compete with a fold out double sided battlemap poster of the two most interesting areas AND electronic versions of all the maps in the issue available to download.
2. A fully functional color e-ink display with a hinged middle and two letter sized displays so I can have my entire physical book library ( of every game ever) condensed into an easily readable portable format. Bonus points if the outer cover is also e-ink and could replicate the covers and spine of the book being replicated.
3. That DnD demo on the prototype Microsoft Surface to have been perfected, cheap, and readily available.
for point2, e-ink refresh rates are pretty bad in ways that make using a PDF on them painful, but calibre can put a lot of things onto ebook readers. Those ebook readers like nook & kindle tend to support a pretty wide variety of file types beyond just epub.
That last point though, I doubt we will ever see those surface tables it ran on again & suspect we won't want them. Look at the nfl hololens video & it's easy to see that table updated for AR as VTTs & AR technology advances but I don't expect it to happen soon.
