Apple Magic Trackpad costs $69. As it named Magic , its not magical, i can only say its is another nice product from apple. For desktop users (Mac mini, IMac) it can be the alternative to Mouse.
As magic trackpad is made of the same aluminum material,same sculpture as of Apple wireless Keyboard, using Apple magic trackpad side by side with Apple wireless keyboard for desktop users looks amazing.


Since Apple magic trackpad uses the same technology that is used on the Macbook pro trackpad but only the size is bigger, its not worth to spend extra $69 for the same feature already integrated on the macbook pro. And off-course who bothers to carry extra pounds on your bag-pack.
