Something I wrote to one of my Facebook friends..
Rewind to before Microsoft defined personal computers and imagine a computer modeled on the toaster or the microwave or the tv (but not the vcr), a device that got out of your way and let you do what you got it for. You push one button to turn it on and instantly you're surfing the internet. No booting, no hourglass. You flick your finger and you are reading your email, like changing the channel. No loading drivers, hiccupped virus updates, hours lost trying to get your sound card or printer working so you can just type a letter or play a song. Another flick and you are watching a movie. This device is a disruptive sea-change, that has the potential to reset what we think of as a computer, and pown the whole decade. The price point is half of what was expected. The battery life is twice the expected. They built their own cpu.
Also note the timing - people are in the process of moving their computing experience online and mobile, as proved by the success of Facebook, the iPhone, and the netbook (which only has enough power to run browser-based apps). Note the branching out and away from the desktop pc, with the rise of laptops, smartphones, and readers. How about the overwhelming importance of media in consumer computing - books, music, pictures, movies, rather than spreadsheets and word-processing. Apple has nailed a convergence of vectors driven by the rise of the prevalence of the Internet in computing. The Internet is the computer, and that thing in your hand, be it kvm (keyboard video mouse), laptop, smartphone, or tablet; is no longer your computer, it's just the way you communicate with your world-wide-web, which by the way, resembles Google more and more every day.
You are going to want one of these.
