The resolution matters in relation to the size of the screen and the viewer's distance from it. If your screen is 32" then 720p is often more than enough, but if you have a 50" screen then you notice the difference more easily.

I agree that it depends on the kind of content you are watching. I know people who use a projector for watching movies at home but a 32" TV for watching TV programmers.

If you just upscale like you said, then you win nothing. The image will actually even look blockier on a higher-resolution screen because of there being less distance between pixels.

The trick is in blending (interpolating) between pixels, but do so in a smart manner.
The simple method is to do linear interpolation, I.e. just let the new pixels have the average of the pixels around them. Lots of TVs do this, but the method is a bit too simple: it will sometimes make things too blurry instead. The problem is to make sharp edges in the image stay sharp and blend elsewhere.
The next step up is to interpolate using curves: plot a curve between pixel values. This will nudge the blended value towards one or the other neighbour depending on the values of other neighbouring pixels around them.

There are lots of even smarter algorithms for upscaling, but the smarter they are the more hardware they require at a smaller gain from the previous algorithm, so at some point it does not become cost-effective for the TV manufacturer to go one step further.
This product is apparently for those who want to pay more for a better algorithm.

What claims?

It is not the way X works is particularly secure to begin with. Once an app has a connection to the X server, it has full control over the world of window, pixmaps and events on the server including of course all other apps.

Not that I have any faith in Wayland or Mir being any better, its developers coming from the X world in the first place, I am sure that they will make their new shiny systems vulnerable in the same ways.

Because focusing the radiation with a parabolic mirror to a single point in the brain is the way to go ...

That's a very good point. I wish I had mod points left.

I require an operating system that isn't crippled, and a full-sized keyboard for typing.
I don't think I would mind a small tablet if it came with a decent OS and a USB port for my HHKB.

Is the TSA kidnapping people now also?

I remember when a co-worker ported a program from Windows to the Mac a few years ago. He had the problem that it made the Mac hibernate every time the program was run.
It took a while to find out why... the answer was that his code had called "Sleep()" with a capital S instead of "sleep()". Apparently, elevated privileges were not required to make the computer go to sleep.

4.3 million SEK is probably a large portion of the movie's total revenue, if not surprassing what it has already made.
It was made for ad-funded free TV for Chris's sake ...

It got low reviews from critics, and the series was already a trite.
Would filesharing it at low quality really degrade it's quality? Sorry, but you can't polish a turd.

(No offence to my cousin's husband who plays the lead in this movie. He's got to eat too...)

In Sweden, forfeiting pets in illegal, but has been done anyway...

Forfeting homes happens all the time, even though there is a severe shortage of apartments for rent.

When I went to primary school back in the '80s, there was a bomb threat almost every year around exam time at the beginning of summer.

Like Chrome, but does not phone home to Google.

Does the D in DHS stand for douchebag?
