I am curious of your application for USB 3? Care to elaborate?

On the Pi 2, the ethernet port was really a USB-to-ethernet port plugged into a hidden USB port. So network speeds were limited to USB 2 speeds. I'm guessing the Pi 3 also works like this, instead of having pure onboard ethernet? But I don't know yet.

If it's using the same bcm2836 chip, then I think it'll have the same limitations. The markings on the chip in the pictures aren't quite legible enough to me, playing around in a photo editor, but it's marked the same way that the Pi2's chip is, from what I could see.

But you can get almost any wireless ability and keep modern with whatever standard changes by simply using a usb stick. They are super tiny now and barely stick out of the usb port. Why hardwire wireless and outdate a board a few years later? I think in 5 years we got g -> n -> 5ghz -> ac and three bluetooth variants. Now there is indoor lte and other stuff coming.

So, how much time did it take you to get the WiFi stack working on your RasPi? Oh? You've never actually tried to get WiFi working on a Pi? Thought so. Getting WiFi to work on a Pi has historically been an exercise in very, very careful shopping for a dongle that actually works. Or getting lucky. Things may have changed recently, but many Pi users have stubbed their toe on the finding-a-Wifi-dongle-that-works rock. Have WiFi built-in that "just works" is going to be hugely beneficial.

Given that USB 2.0 is 480Mb/s, and Ethernet is 100Mb/s, there is no bottleneck when using the Pi's Ethernet port. I really wish this myth that "Pi Ethernet is slower than dialup because USB" would just die.

Of course, like everyone else I'd love to see a new version of the Pi with Gigabit Ethernet directly connected to the system bus, and USB 3.0 while we're at it. But that would greatly increase the cost of the device and also require a newer SoC that supports such things.

Get a Chip!

Seems like you'd get a Pi Zero before you'd get a chip. They don't start shipping until June, and I see Zeros in stock for a few seconds (some on Adafruit yesterday, although they sold out in seconds).

I have a CHIP, from the Kickstarter campaign. It really is a better deal than the Pi Zero, unless you have Pi-specific needs. It's much more powerful than the Zero in my testing (though not quite as powerful as the Pi 2) and the built in Wi-Fi/BT is awesome. The fact you can attach a LiPo battery and have it managed by an onboard power regulator is worth the whole $9 as far as I'm concerned.

The only downside is no HDMI or even VGA until the respective adapters come out...in June. I currently only have one screen in the house with a composite input and it's not always available for tinkering.

+1 for Retropie. So much fun. If you have a Raspberry Pi sitting around that you don't know what to do with, just do this. You won't regret it.

If I may add - do yourself the pleasure, and use a standard usb Xbox 360 controller, otherwise you are in for a world of pain. I've tried a NES30 controller over bluetooth and after a week of trying different configurations nearly chucked the whole thing in a bin. Also some of the emulators are too slow to be usable, even on the Rpi 2, NES and SNES work absolutely fine, but MAME, N64 and Dreamcast are more like curio…

Goldeneye works quite well on a rpi2

I think some of that has to do with the fact that a lot of those older games aren't really as fun as we remembered them to be. There's some classic gems, to be sure, but they were also all we had.

The bigger underlying problem is that we associate those games with happy periods of our lives. The once where we could play games, do projects and not worry about anything else. By playing an old school game, your brain extracts these happy feelings from the memory. However, it's not a sustainable source of "fun" per say. As opposed to the newer games where "fun" is being caused by the game directly.

I strongly disagree. I have zero interest in today's bloated AAA games. Simple games like Tetris, Mario + romhacks, or Civ II have given me collectively more fun that I would ever have playing some insipid shooter or uninspired pay2win fantasy game. I wouldn't trade them for any of today's games, which I consider severely flawed in many ways.

Raspberry is the most important project that made my family interested in "computer things" It gathered the whole family together to play old couch-games[0], something that most powerful consoles haven't even been close --specially with the grampas Really exited about what the future will bring us! 0: http://emulationstation.org/

I must be the only one disappointed with old-school games. I was super excited to set up a retropie, after 20 minutes playing the nostalgia wore off quickly. Anyone else find the same?

I totally not feel that way. I've had more fun playing Fire Emblem games lately than I had with any game released in the past 5 years.

Another downside is the size of the community. I think this is why the pi is going to be around for a long time despite not having the best tech specs around. There are all kinds of tutorials for hundreds of projects and the prevalence and availability of rpi forums further lower the barrier for entry.

It's now easy to find reviews on amazon for many wifi dongles specifically mentioning rpi compatability. And they just work.

Im sure you could still buy something unsupported if you didn't do your homework, just like nearly anything.

I can't find any info to say which bus the MMC reader is connected to, but I know if you use a USB drive as well as the built in ethernet port, speed will suffer.
