Two things went through my head when I first learned about this. One, I'm all over this: I'm all for anything that can free me from using a mouse, especially something this cool. Secondly, I started thinking about what this will mean in education and industry. I posted on the leap motion forum about how great it would be if each student in a classroom had one of these on his or her desk and could take turns controlling something on the class smartboard. While teaching math, for example, a student could raise his or her hand and could demonstrate how he solved a problem. And that is just the tip of the proverbial iceburg. They're already coming out with a bunch of apps and I will be chomping at the bit to start playing with them.
For now, though, I can only just search the net for information: it may be a month or 2 before I hear anything about my pre-order. I'll post back here as soon as I hear anything.
