I admitted that tablet computing is in its infancy and will take time to mature. The iPad is just getting multi-tasking when the Mac has had it for 15+ years. Is it possible that Mossberg and others see the potential of the form factor and UI? That more "level-headed" reviewers just can't see outside the box? Do you really believe we'll be using a mouse in ten years? Or a keyboard that hasn't really changed since the days of typewriters?
Since the beginning of computing, the ideal form factor has always been a tablet. If you watch Star Trek or other futuristic sci-fi, that's what you'll see. Apple has made the first tablet that's not a pain to use. This is huge. This is why journalists are going crazy over it. Look at how much laptops have changed in the last ten years. Then imagine tablet computing ten years from now.
On the eye-strain issue, I'll ask again. Don't people stare at a monitor for 8 hours a day at the office? What's the difference? Almost all writers write on a laptop (except a few who still use a typewriter). They sometimes write for 16 hours at a time.
Potential for the form factor? Okay. Saying it will be the potential end of laptops? No. Absolutely not.
The only concession I'm willing to give the iPad is that it gives us the option of something beyond a laptop with regards to consuming media in our travels. If you never truly needed that laptop's keypad during your vacation, well, now you don't have to bring it along. I recognize the freedom of that choice. But at the same time there are so many drawback (IMO) to the current iPad that I can't justify it as any sort of future model for computing. Perhaps if they place something more similar to Snow Leopard and put a widescreen on it (for watching movies PROPERLY and using that extra space for a better onscreen keyboard). I look at the iPad and I simply do not see the future. No matter what any reviewer may proclaim. The iPad is a great way to consume things and give Apple your money for apps and movies/tv shows. That's what I see.
Do I believe we'll be using a mouse in 10 years? Tell you what, I DON'T believe we'll be touching our screens for our desktop computers. That's for sure.
Just because you saw a tablet-like device in Star Trek doesn't mean a thing. Please. And with regards to laptops, yes, they've gotten better in many regards, but their form factor (screen and keyboard) is essentially the same as it was 10 years ago.
