The "Inverted-T" arrow keys here are way better than the previous version with full-height Left/Right but half-height Up/Down.

But I've always preferred the "6-key" layout, as seen on ThinkPads. Half-height arrow keys, but then an additional key on top of both Left and Right.

Commonly marked as Page Up / Page Down, but easily reconfigurable to 2 additional arbitrary hotkeys.

Looks nice and symmetrical enough for Apple. Wish they would use it.
