Integrating directly into clothes is not something I really believe in (I tend to change my clothes every day - but of course there is the trend towards mobile devices and computers converging into ... Well, or lets say mobile devices gaining most of the capabilities of traditional computers.

Then again, I personally wouldn't look at this from a technological standpoint, but rather from user need / human behaviour. The technology will come one day anyway, it's more about what do you with them and how.
