Hmm... I might be off by a year or two, but I think it's pretty #%!*^&% amazing that you can have a powerful computer that is a link to the world in your pocket. That was the deepest science fiction 20-30 years ago. Maybe it's due to cheap flash memory, or maybe flash memory itself. No matter, it's pretty amazing.

Yeah, it would be quite nice to have alternative energy sources that were inexpensive. It would also nice to have cures for all "popular" diseases. But, compared to mucking with computers, those things cost serious money and require serious hardware. Oh, and can't be solved by "release early and release often".
