Mostly due to batteries. If you compare the power usage of laptops then, and now, you'll find that older laptops tended to use in the 10-20W range for their motherboard and CPU. Modern ultra books use a similar power level, while modern laptops use around 30-50W, and still get longer battery life.

No, mostly due to higher IPC, agressive power gating and deeper sleep stages. Here's the extended battery pack from my 2002 UltraPortable, 3600 mAh in 330 grams. In 2014 the extended battery for the Sony Vaio Pro 11 is 4690 mAh in 290 grams, that's about a 75% increase in power/gram in 12 years. There have not been any major revolutions in battery technology, it's still the same lithium-ion technology just a little more refined.

You're not comparing just the weight of the energy storage element, but also the weight of the casing. And that has changed a lot in the last 10 years.

Apple have since day one insisted that everything in their computers be usable with single-button mice. Why? Because of user friendliness towards people who aren't comfortable with computers.

As a result Apple brought the world the double-click.. which is far more confusing to users than a second button.

I agree.

Spreading viruses via abandoned USB thumbdrives is probably the *least effective* and *most expensive* way to do it... it's just not happening in real life.

If you find a thumbdrive, it's going be the result of someone losing their thumbdrive. The odds that it has been rigged to infect your computer are so small as to be non-existent.

Because neither will last forever. We could sit around until it's gone and then react to the catastrophe that follows (like we do with bridges and levies and education) or we could try some new things at relatively minimal cost in the meantime.

Hydrogen, being only a storage medium, is not a replacement for neither also. So the problem that "they will not last forever" is not being solved by those "new things".

You completely ignored his message.

(Some guy in 1960: "Why build this Internet thing when we already have phones and telegraphs and cans with string? We already have plenty of ways to communicate, why do we need one more?")

Not a valid comparison.

That means that the only way we can make any money at all is to ramp our price up to substantially higher than the recommended retail

You can't even do that.. Apple forbids you from charging more than anyone else.

So you have to charge the same amount as Apple does in iBooks.. but Apple gets 30% of your income.

Color me Naieve, but when did Apple charge software developers in the 80's and 90's for Mac development?

From the very beginning.

When the Mac first came out, you had to buy a Lisa and Lisa Workshop to do Mac development.
Then MPW came out a few years later, and you no longer had to buy a Lisa.. but MPW was *not* free until after XCode came out.

Basically, until XCode, it costs thousands of dollars to develop for the macintosh.

It's a bit like using a steering wheel lock in your car. It's not that they can't be defeated, it's just that there's no point wasting time trying to defeat it when there are plenty of cars without one.

Depends on the lock you're talking about. If you're talking about the lock built-in to pretty much every steering wheel, then fine. If you're talking about The Club, then bad analogy.

Thieves actually target cars that use The Club because they don't have to carry an incriminating pry-bar around to break the built-in steering wheel lock.
