Wireless!!!
I am sitting in my office posting from my laptop!!! They installed the equipment a few days before Christmas and, after a bit of a false start, it works! They thought because of the way the building is constructed that it would only work downstairs, but we have three and four bars all over upstairs. Between this and the MP3 player I am full of geekly squee. Dang, now I have to convince myself to actually work.
