Just looking at the title, I was (almost) wondering if it would be honeycomb-shaped... but apparently not. A hexagonal device would have been interesting though. Who says a tablet has to be rectangular anyway? :)
I've did a bit of experimentation with hexagonal layouts in the past, just for fun (hexagonal grids have some useful properties). But is has some problems that make it very unconvenient to use: for example, you can't subdivide a hexagon into smaller hexagons. This makes for really wasteful layouts :)
