There are a lot of iPad accessory options out there but they don't turn the device into a laptop, or into something like a laptop. Even if someone uses a keyboard to write emails once in a while they don't likely use the keyboard for Web surfing, reading maps, or for any of the many other tasks to which a tablet is better suited than a laptop. Also I think you are severely overestimating how popular these accessories are compared to the iPad itself. Frankly it's nice that the iPad is flexible enough to accommodate a variety of usage scenarios, unlike a laptop.

I'm sort of sad to see so many Slashdotters responding so poorly to tablets, which are the most important development in computing in a decade. We ought to be leading the charge forward and demanding tablet casemods and overclocking. Instead we are whining that a screen attached to a keyboard via a hinge is the One True Way. Laptops were designed for office work and they do not make very good home personal computers.

The big question I have is if it will be like AMD's previous 12-core chips, where you could get 4 of them crammed into a 2U server for not all that much money. 4-Xeon configurations are way more expensive.

God dammit, Slashdotters are so dumb about corporations and how they work. Even if you're anti-corporate you ought to know a handful of things about your enemy.

Suppose you are a corporation with basically one physical asset: a $10 billion TV factory. Raw materials and labor go in one side, and finished TVs come out the other. Let's even ignore R&D and marketing.

What you'll learn very quickly is that you can't really control the price that you sell the TVs at. Since you have competitors also making TVs, and there is only so much demand for TVs out there in the market, you're constrained. Maybe some of your competitors can build TVs cheaper than you because their labor is cheaper, or they have a better factory, or whatever. Maybe everyone expects huge TV sales due to some new technology and the sales never pan out, and there are just too many TVs in the market.

So your brilliant idea is to shut down the factory the moment that you can't sell the TVs for more than the cost of making them. In the real world it isn't always so simple. If you completely abandon the TV market, you'll have to sell your $10 billion factory even though nobody wants a TV factory right now -- you'll be lucky to find a buyer at $1 billion. If you decide to sit on your factory (still paying for maintenance, security, property taxes, etc), you'd have to get rid of your employees to really save money, and then you'll need months of lead time to re-hire people if the market picks up again. Not to mention that you'll lose your position in the marketplace -- everything from distribution contracts to your mindshare will evaporate. Nobody really wants to buy or distribute a TV from a company that only makes TVs some of the time.

There is always a point where keeping things running isn't the best decision, especially if you think the market will never come back (the buggy whip situation). I'm just saying that the point where you start selling things for less than it costs to make them isn't always the time to abandon production. Sony will be happy that it kept its TV division running if the R&D guys can come up with some new feature that everyone actually wants to buy.

Bottom line: yes it's possible that they really are losing money on each TV. Depending on how you interpret the mysterious future, they might lose even more if they stopped making them.

Not sure that the keyboard dock will prove that popular with the general public. It's almost forgotten now but Apple sold a keyboard dock accessory for the original iPad on release day. They don't bother to make it anymore due to low sales, but the iPad is still compatible with Bluetooth keyboards (as it always was). The general public hasn't had much interest in that either, though a small Bluetooth keyboard plus a small iPad stand is occasionally useful for sending email or using SSH while traveling or whatever.

Twitter is for things you like. If there's a local restaurant you like, maybe they will send notices of their daily specials now and then. If there's a musician you like, maybe they'll let their followers know that tour dates have been announced or that their new album is almost out. Going to a convention? The convention feed might let you know when event schedules change. Maybe a columnist you like will make occasional points that supplement their regular writing.

"But we have email!" I guess you are saying. Ever subscribed to an email newsletter from a restaurant? You'll get 5MB PDF coupons, only good on Wednesday afternoons, as likely as not, and good luck with the unsubscribe. Twitter guarantees that the messages will be small and it's always easy to unsubscribe.

Don't know why it's so hard to understand -- there isn't any other service that's good at this.

I have to ask: is "sweat-of-the-brow argument" an actual legal term?

DJIA isn't weighted. Where are you all getting the idea that DJIA is weighted?

That's not true; the Dow is even simpler than you are implying. There is no weighting at all applied to the individual stocks in the index, so it's incorrect to say that they weigh "each stock price with a factor". Instead, there is only one factor (the Dow divisor) for the entire index. All the share prices are simply added up and then divided by the divisor.

When AAPL was added to the Dow, the Dow divisor would be adjusted to account for the difference in price between AAPL and whatever it replaced, but that's it. So it's completely incorrect to say that a 5% change in Apple's price would have the same influence as any other company. In fact a 5% change in a high-priced stock would have much greater impact on the Dow value than a similar change in a low-priced stock.

Yes, the DJIA really, really is that bad of an index.

Apple pretending that they had no intention to allow apps on the early iPhone was obviously misdirection in retrospect. At the time they were having enough trouble making the software work at all without crashing, and they didn't want developers/users to avoid it while waiting for the bright app future. Sort of a counter to the Osborne Effect.

So is using an iPad as a cookbook "content creation" or "content consumption"?
