Dana Wollman comparing the Motoactv to the iPod nano at Engadget:

With its square shape, 1.6-inch touchscreen and raft of fitness features, it’s impossible not to draw that parallel as soon as you even read about the thing. Without the clothing clip attached, they’re similarly, sized, too

Oh come on, seriously? I think John Gruber summed it up perfectly.

I’m not sure if they’re ripping off Apple’s iPod Nano, or Samsung’s business model of ripping off Apple designs.
