He only means that you're ignoring the lessons of the past when talking about the tablet. If you can't see that, go ahead and keep claiming that a tablet is useless.
Oh I can see that. Apple has had a lot of hit and misses in the past. Not every Apple "revolution" has been one. The iPod is one example. Shiny plasticy transparent cases were another. However, stuff like the Macbook Air was one too, the Newton, heck, even Apple TV in a sense.
Let's forget it's a Apple product for a moment and just think the uses of a tablet. It's not ergonomic to type on, it's not anymore probably than a 10 inch laptop would be and without a full featured OS, it would be just a big iPod Touch, which kind of defeats the portability issue.
So it's not an issue of drinking the kool-aid and going all doughy eyed on it, but what is the actual market and use for a tablet that the iPhone/iPod touch or a Macbook don't already fill ? Students taking notes ?
Do you think that we'l be using a keyboard and mouse forever?
It's a tablet because you can take it with you around the house or on the go and do most of what you need a computer for on it. Most people don't type long messages like this in forums - they may write a quick facebook message or email or something. And for this a virtual keyboard will suffice. Nothing beats a physical keyboard right now, but that's not going to stop technology from evolving. Having a physical keyboard on a device like this would at least double the size and complexity of the device. (see: current tablets with rotating displays, etc.)
Multi-touch is revolutionizing the way we interact with technology, and a tablet is the most logical computing device to implement it due to its portability and generally non-heavy usage.
Wait, keyboards are dead, long live virtual keyboards ? Because somehow replicating a keyboard virtually on a screen that is touch capable makes for ... a... better... input device ? Put down the pills son, screen realestate is already a rare commodity, I don't need a keyboard taking up half of it.
Around the house, I use a laptop. Haven't had a desktop computer in about 3 years. All your ranting about super-portability doesn't change one fact : Typing on a laptop while reading the screen is comfortable. The screen is propped up, the keyboard is laying flat. Holding a tablet like a clipboard in one hand and type on it with the other isn't. Laying it flat on a table isn't comfortable either.
You've put your finger on it. People nowadays that want to Facebook or tweet or just plain have a web capable device on the go use a iPhone, Android phone, Blackberry or anything else in that format. When they get into the office or home, they use their laptop/desktop to do actual work.
The fact is, the tablet doesn't sound like something that's portable enough (vs an iPhone) or useful enough (vs a laptop/desktop) or ergonomically comfortable (vs just about everything else).
