Southpaw-only model isn't just another ambidextrous product.
Just to be clear, we don't have anything against specialty mice--quite the contrary, actually. We just like to see features that make sense, such as this model made specifically for lefties.
It's obviously not the first mouse of its kind, but most of the ones we've seen are made to be used by the ambidextrous. And we think that's a two-handed slap in the face to natural southpaws. On the other hand (OK, we'll stop), the awesomely named "Cherry Ergo-Shark" is made for only for left-handed mousers, a wireless navigator with seven buttons, four-way scrolling, and a Teflon sliding surface, according to SlashGear.
Thumbs up and high fives all around.
