Ok, so I am a salsa geek too. Yesterday I got my third pair of dance shoes in two weeks. I did not exactly plan to have three pairs, but I could not resist buying two pairs on sale when visiting World Tone Shoes in NY. The third pair I ordered many weeks ago, but they did not arrive until yesterday.
For some time while dancing in New York, I did not feel so much a geek, but now... My Logitech Marble Mouse has arrived. It is the only trackball from Logitech which was not intentionally designed for the right hand. The Marble Mouse has a smooth design, and it is easy to use and get used to. The only disadvantage I have discovered so far, is the lack of a scroll wheel.
