This is a really, really cool piece of technology and NASA really needs it, but IMHO it looked out of place in the inauguration parade. I was glad Obama perked up when he saw it, but it could just as well have been a Mickey Mouse float and it would have evoked the same reaction. Again, your mileage may vary, but for me it was a hokey advertisement for NASA. At least they didn't set out a tray of rusty dirt for a spacewalker to leave his footprint in (i.e. a not so subtle hint from NASA administrator Michael Griffin to stay the space course).
