If I want a low end system it seems like I can't build one for less than Dell/HP/Acer/Whatever sells them.

I suppose it depends on how "low-end" you are looking for and how long you want it to last. One of my biggest pet peeves with pre-built systems is the power supply they put in them. Half the time they don't even meet the minimum recommended voltage and leave no room for additional drives or video cards. Nor do they leave any room for capacitor aging. They also have a very high failure rate, and are terribly inefficient. So long term, they don't do you much good.

Cheap PSU's also tend to like company in their failure. I learned that the hard way 20+ years ago when one took out pretty much everything in the case but the fans. I've had two quality powers supplies die and didn't do anything to the other components. One arrived defective and started glowing and released the magic blue smoke before I was able to unplug it. But nothing in the case was affected.

I suppose if you are looking for the cheapest thing you can find and don't care if it lasts more than a year, prebuilt is the way to go, but I don't have much use for that.

I went on an upgrade binge about 3 months ago. I got a new CPU, additional RAM, a larger SSD, and installed a video card that I've had sitting around for the last year or so. I also replaced the fan on the CPU cooler with a Noctua fan in my main workstation. But I reused the case, PSU, spinning disk, DVD reader, Blu-Ray burner, and DVD burner. As well as the monitors, KVM, mouse & Keyboard.

I got the fastest possible CPU for the old board and re-flashed the BIOS. Then put that in my secondary workstation with the VGA and one of the old SSD's from the other workstation and reused everything else.

While I was at it I also upgraded the CPU in my file server to a faster more energy efficient one and increased the RAM as well as swapping out a bunch of 1 TB drives for some 4TB drives.

The media room PC got a new MB, RAM, CPU, video card (fan-less), and heat-sink/fan and all fans replaced and a new SSD.

It's the first time I've upgraded in 5 years.

But being a man, I was always smart about which cigarettes I bought. I never bought the ones that caused cancer and all that other scary shit. I only smoked the ones that caused low birth weight and pregnancy complications. I figured since I would never be pregnant, those were the ones to go with. I could never figure out why the brands would keep switching though. ;-)

My dog kept dropping the video camera when my wife and I wanted to make an intimate recording. Jibo won't do that.

Ergo, Jibo is much better than a pet.

My pet is a Doberman. Actually three of them. They kindly let would be burglars they're at the wrong house. In your situation a tripod will probably suffice.

Ergo, a pet is much more functional than a Jibo. As a bonus, they aren't obsolete in two years either.

What they didn't say is that Neymar shows only 10% brain activity compared to another "common" person for whatever he's doing...

So you're saying he's more intelligent than the "common" person? It's been understood/believed for some time that that the more intelligent a person is the less their brain has to work at similar tasks.

According to Google, the information from Baseline will be anonymous, and its use will be limited to medical and health purposes.

I work in the medical field. Both clinical and research. I've seen what "anonymous patient" data looks like. While it can be done correctly, it almost never is. When I say almost never, I mean under 5% of the time; and that's being generous.

The DICOM data generated by most advanced imaging scanners (MRI, CT. etc) is pretty big. To make matters worse, every vendor (Philips, GE, Siemens, etc) uses more than just the standard fields (tags) to store the unique patient identifiers. They all also use proprietary or what are sometimes referred to as "shadow" or "private" tags. These tags are different for every vendor and are used in different ways. To make matters worse, these tags can change depending on the model, firmware version or even the scanning sequence used.

If you just remove just the standard patient identifying tags, you could very well miss that they were all duplicated in the private tags. If you simply remove all of the private tags, you may end up removing the very data that is needed to make sense of the images themselves. Such as how many mm a pixel is, or the volume of a voxel. This all needs to be done for every image in the exam and there can be thousands to tens of thousands of them. Most programs used to de-identify the exam either miss all of the private tags, or remove too much data and render the exams useless. So patient identifiers are left in most exams and we just try to ignore this.

The big question is, is how will a company like Google treat this unfortunate situation? Most in the medical field are there because of their compassion for their patients and do research for the betterment of the general population. What happens when executive types realize they have this kind of data?

something small enough to fit on a phone while still being useful for a 60 inch TV or 120 inch projector.

What are you using to compress and into what format? My phone (Galaxy S3) limits me to a max file size of 2GB. I've yet to find a way to compress a movie into 2GB, or less, and maintain enough quality to view it on a 60 inch TV, let alone my projector without a very noticeable drop in quality.

"Vital For Possibility of Earth-like Alien Life"

A lot of assumptions there.

We can't even communicate with other species here on Earth in the same Class as us. Elephants, whales, and dolphins show signs of intelligence. Certainly enough to communicate with each other. And we've hunted species of two of them to the verge of extinction. The Great Apes are in the same Family as humans and we can't have a meaningful conversation with them. Perhaps they are simply too primitive. Or maybe we aren't as smart as we would like to believe.

A non-terrestrial species may communicate using some form of telepathy or chemical component. That would be fun to try to figure out. Or use gravity waves over long distances. What if they are silicone based and live for thousands of years. It could take them 3 days to say hello using subsonic vibrations.

Until 20 years ago we didn't even know that Elephants could use bone conduction through their feet to listen to subsonic calls from other elephants that create seismic vibrations. Or that they also had cells in their feet that are able to pick up vibrations in the ground.

ET could be screaming at us right now and we don't even The messages could have been sent through cosmic radiation and is encoded in cancer cells. They may have thought that would be the easiest way to get our attention and we just haven't picked up on it yet.
