I like the new device, but I am a bit worried/concerned about the arrow keys. In other Macs, the left and right arrow keys take up a half-height key height, but in this Mac, it takes up a full-height key height. In other Macs, this means I can easily and blindly find the arrow keys, just by feeling where the gap is above the left/right arrow keys. In this rMacbook, it seems this isn't the case. There isn't a thread about this, so here you go. Am I too worried? Will all be fine in the end?
