Fine finish, very well studied ergonomics (comfortable for all hands, to my children long adult fingers), great battery life (6 months for 2 AAA) and funky design (nano receiver can be housed in the battery's compartment, it who goes to sleep mouse automatically).
And laptop does not mean limited because we note the soft keys on PC and MAC, the laser sensor, the variable scroll-wheel, the carrying case all cute and finally full support with USB cable for use as a mouse fixed computer!
And yes sir! (Or Madame)
