New invention ideas?

[MAC]

Some might complain this is not H2 related, but nobody visit the Off Topic section anyway. Just for fun and irrelevant conversation.

What new invention concepts you think there should be, can be or whatever? maybe should limit to possible stuffs? if you want to list things Hummer should have or could have, that's fine too.

Why CD? why not all music CDs are video MTV DVDs? why so big, should be smaller type of disk.

One day all camcorder and high resolution digital camera will be true card size all in one, as thin as a credit card. Heck, the cell phone should be in there too, we may need smaller fingers. I have too many small things to grab on my way out.

Virtual screen and keyboard, you can cut 80-90% of the size and weight of a laptop. Not much different than in Final Fantasy movie.
