Many people think that Playstation 5 is ugly, myself included, but its design is to help keep it cool. It has a huge heat sink to cool it down. The much smaller but more powerful XBox Series is reportedly getting very hot according to early reviews.

Why Does Wi-Fi Use the Same Frequency as Microwaves?
The other day I guessed that a router would broadcast at only 0.1 watts, which would make it about the same power as a cheap walkie-talkie. In theory, the 5ghz band allows for higher speed, but shorter range.

Wi-fi problems with new AT&T Internet
I have resolved my Wi-Fi speed problems as best I can. It turns out the latest Broadcom drivers for Windows 10 are not good, at least not for high speed. Initially, I was getting only 30 Mbps. I did much research on the Internet, and I saw a few different websites and videos recommending switching to older drivers, a couple of which I had to download and install. I have switched between 4 versions of the drivers, and the oldest one seems to work the best. My speed tops out at about 200 Mbps, although reality might be a little less. I did a large download to test the speed and I calculated about 120 Mbps, which is at least double the speed of my old internet.
However, the same computer running Mac OS gets up to 660 Mbps with my new AT&T internet. My iPhone gets about 400 Mbps. One option for me is to run an ethernet cable to the router, which would work, although in my current setup that would not be convenient.
The AT&T technical support couldn't do much other than test that the internet is working. They recommended that I do a Windows Update, which took an extraordinarily long time and didn't help. It was also recommended that I reinstall the Bootcamp software, but for some reason, the install crashes and does not finish. I tried manually copying the driver from the Bootcamp software, which helped, but I got better results by downloading and installing an older driver.

It was slightly helpful to turn off power saving features on the ethernet and wifi cards by selecting "maximum performance" instead.

It seems odd to me that the Microsoft Windows Update installs the latest Broadcom driver that is apparently defective. This could happen with my next Windows Update and I'll have to fix this again.

Is the Smartphone Market Ready for This?
Apple has the only 5 nanometer processor available to the public so far. It is no wonder that Apple is dumping Intel and going with their own chips on future computers.

This performance is comparable to my old Core-i7 iMac computer. On an iPad Air.
What is astounding is how many nodes per second Stockfish gets on my five year old iPhone 6s+. Around 2 million. On my 2017 iMac I see 3 to 5 million.

Apple details A14 chipset ahead of iPhone 12 lineup announcement - GSMArena.com news
Right now, the only 5-nanometer computer processor in the world is on an Apple iPad Air. However, AMD is not far off. Intel, however, has been struggling to keep up. They only recently introduced 10-nanometer chips.

Rock Pi 4C: Dual Display M.2 NVMe SBC
https://www.youtube.com/watch?v=BTyIFZPgBT0
I bring this up because it seems like much power for the money. I am impressed with what single board computers can do. The CPU benchmark is about 2/3 of my laptop and about 1/3 of my desktop computer. Of course, you are stuck running Linux.
The Raspberry PI 4 is much more powerful than the Raspberry PI 3 that I have. Still, it benchmarks like a very low-end laptop.

Microsoft Just Revealed How INSANELY POWERFUL The Xbox Series X Will Be.
https://youtu.be/3qreWiBtcFY
I've been interested in how powerful the XBox Series X is going to be, because I can't build a computer this powerful for $1000, and maybe not even $1200. I want a computer with this much power.
Well, this video reveals that the custom APU chip, the central processing unit with the GPU built in, is going to cost over $500 by itself. That doesn't include any other parts.
Rumor has it that Microsoft plans to take a $200 loss on the system. The rumored price is $599. They can make that up with subscription services.
I want AMD to sell me the APU. It will never happen. They have revealed plans to release a video card with the same GPU technology.

How Nebraska elites screw farmers & get away with it.
https://youtu.be/r2AqVfIrjZ0
In theory, if I don't like Apple's repair policies then I don't have to buy Apple products.
However, I feel like Apple has engaged in some monopolistic practices that are pretty questionable, like using the law to throw someone in jail for charging a nominal fee for burning an install disk on software that Apple gives away for free, and using the customs agency to confiscate refurbished Apple parts as "counterfeit", even though the Apple parts were sold as refurbished.
Apple should not try to monopolize repair manuals and repair parts in such a way that only Apple can do the repairs. Most of the time Apple will tell a customer that it is way too expensive to make the repair and that the customer needs to buy a new item. One extreme example of this was when Louis Rossmann was able to repair a loose connection in a couple of minutes that an Apple repair person said would cost $1,000 to fix.
When I buy a product, especially an expensive product, there is an implied contract or at least assumption that if I need it repaired then I can get it repaired and at a reasonable cost. If a company deliberately makes this difficult or monopolizes the repair service, then I feel that I am being denied reasonable choices that I should be allowed to make.
This issue is by no means limited to Apple. This is spreading to other products as they get more high tech.
Government interference in the marketplace often causes more problems than it solves, so I don't necessarily have a good solution.

Google's Friendliest Smartphone - Pixel 4a
Maybe because of competition, we are entering an era of cheaper mid-range phones that have some really good specs. The new iPhone SE has top-notch internals and camera with a 4.7" screen. However, I prefer my 5.5" screen on my iPhone 6s+.
This low-cost Google phone has a 5.8" screen.

Commodore History Part 3 - The Commodore 64
This guy is a huge Commodore 64 fan, understandably so. However, in terms of inflation adjusted dollars, it was expensive in 1982, like $1580 in today's dollars. Even more so if you bought any of the many Commodore 64 accessories.
A company called Sinclair came up with a cheap computer called the Spectrum that was enormously popular in England and Europe, and Timex sold an upgraded version of the Spectrum in the United States.
https://www.youtube.com/watch?v=BpXFB8ZEH30
So I had to write this:
"In 1983 I got a Timex Sinclair 2068 for $200. It also had a great sound chip and a 3.58 MHZ Z80 and a keyboard that I actually liked. It had many advantages over the Sinclair Spectrum. It was much computer for the money, compared to the $595 for the C64, equal to over $1500 today, which for me was way cost-prohibitive. I temporarily had a healthy business selling software I wrote for the 2068. I loved this machine. I'm sure that I would have loved the C64 more with the better graphics, but the cost was a huge issue."
I am actually very proud of the business that I ran selling 2068 software. This helped me get computer jobs later, and eventually, I worked in the console videogame industry.

Re: PC vs Console 2020.... Uh oh...
I see various prices, but the RTX 2080 costs at least double of what the presumed price ($500 to $550) of the XBox Series X is going to cost. In fact, the new consoles reportedly have so much power that I think that they will be initially $600 to $700, with the price coming down later as the parts become cheaper. Microsoft claims that they are going to take a $200 loss on their game system, but they are going to offer a monthly game subscription service which would likely be profitable for them.
I heard a report that the PS5 costs $450 to build, but even though it is not as quite as powerful as the XBox Series X, it has a more expensive SSD, so it hard for me to imagine that they could build it for so little money.
My main interest is how powerful the AMD APU's are in these things for presumably lower cost. I want the same deal in a desktop computer, but I'm not likely to get it. At the moment it would be very expensive to build something comparable, like at least $1500.

AMD's most important product ever - Ryzen 9 4900HS
It is amazing what AMD is doing with processors. This mobile processor benchmarks at 246% of my 2017 3.4 GHz Core-I5 iMac.
AMD is accomplishing this with Zen 2 architecture. Zen 3 releases at the end of the year, reportedly with 15% better performance The new gaming consoles from Microsoft and Sony coming out for Christmas will be using AMD Zen 3 chips.

Re: iPhone 4: 10 Years Later - 2020 Review
A few years before smartphones came out, I bought a very cheap digital camera. The resolution was like 1/4 megapixel. I think that it was 640x480, but it wasn't that long ago, 20 years, that this was a standard computer monitor resolution. My monitor at home was probably no better.
At that time, 2-megapixel cameras were expensive, like $300. The funny thing is that the cheap camera actually took decent pictures at least compared to what I was used to, which wasn't much.

I really loved the iPhone 4/5. It is still my favorite design. The bands on the side gave it a sturdiness.
I was in Salt Lake City on a slope near the base of a mountain where I dropped the iPhone 5. It went bouncing on pavement downhill but suffered only very minor scuffs on the corners.Because of the Antennagate on the iPhone 4, there was a problem with the signal not being as strong if your fingers crossed a certain spot on the external antennas, but it wasn't much of a problem for me. As a result, Apple gave everybody a free case, which I got, but I didn't use it much.I was actually pretty happy with the iPhone 4 camera. There was a time when 5 megapixel was considered premium.
