New Style, New Color!
I've had the white Wii with white Classic Controller since launch. I've been waiting for a black version ever since.
I much prefer black consoles over white, and this doesn't disappoint.
While the old controller had the classic SNES-style roundness, the new handles make the controller easier to handle.
And as for the Z buttons, I much prefer the new PSX-style R1/R2 (over/under) compared to the old R buttons on the inside.
Overall, the color is what made me buy this but I've found that the new layout just adds to the old controller style, improving on an already good thing.

A must buy!
This is a much needed improvement over the old classic controller, Looks a lot like Sony's Dual shock controller but feels more like the Xbox360 controller. Great for playing games such as Muramasa and A boy and his Blob.

much more comfortable
This definitely feels better in your hands, compared to the original classic controller. A must have if you are into the retro VC games!

good controller for monster hunter
it's pretty good controller for Wii RPG games

Very convenient controller for Wii
It's quiet useful for playing games like Monster Hunter 3. However, the feeling of the analog stick and L/R key lack flexibility and not as good as PS3 or XB360.
