This is now old news, but it definitely has had and will continue to have an effect on future computing. In January, Steve Jobs introduced the MacBook Air at MacWorld:
Although I haven’t yet had an opportunity to use a Mac, I love the look of it. Beautiful to look at, quick to boot, and light! There are a few drawbacks — no internal CD/DVD drives, a user cannot replace the battery, the USB port won’t accommodate all USB gadgets (but you can purchase an extension cable to fix this), and price. Engadget has a review of the laptop which provides even more details.
As usual, though, Apple has moved the target — good going!
