Regarding "End next to up key", it's the same as on the Carbon X1 which to be honest, is kind of comfortable. I'm using the arrow keys to scroll on pages when reading, and when I want to skip, the keys for that is right next to it.
At pictures I see PgUp/PgDown keys next to up arrow. Dell has it the same way I think. It's a bit different to an End key, but even then, the biggest issue was that it's only the End there. No Home on the other side.
