Has anyone had success using an ARM based system for local development in Linux?

Oh my! This is such a crazy upgrade. I've been using the RPI2 as my HTPC/NAS at my folks, and I'm so happy with it. I was itching to get the last one for myself.

USB 3.0! Gigabit Ethernet! WiFi 802.11ac, BT 5.0, 4GB RAM! 4K! $55 at most?!

What the!? How the??! I know I'm not maintaining decorum at Hacker News, but I am SO mighty, MIGHTY excited!

I'm setting up a VPN to hook this (when I get it) to my VPS and then do a LOT of fun stuff back and forth, remotely, and with the other RPI at my folks.

Oh this is great. WiFi and gbit ethernet onboard is what I needed.

Is USB and network bandwidth still shared?

Possibly, but usb3 is a lot faster.

"The Ethernet controller on the main SoC is connected to an external Broadcom PHY over a dedicated RGMII link, providing full throughput. USB is provided via an external VLI controller, connected over a single PCI Express Gen 2 lane, and providing a total of 4Gbps of bandwidth, shared between the four ports."

Better than one could've hoped!!

Depends on what you are doing.

Nope, it's completely unfettered by USB this time.

Nope, according to https://opensource.com/article/19/6/raspberry-pi-4

> The BCM2835-based chip in Raspberry Pi 1 to 3 provided just one native USB port and no Ethernet, so a USB hub on the board provided more USB ports and an Ethernet port. The 3B+ added a dedicated LAN chip, which gave it Gigabit Ethernet, but this was limited to USB2 speeds. The Pi 4 has dedicated Gigabit Ethernet, and because it's no longer throttled over USB, its networking speeds are much faster.

Cool. Mathematica would actually be usable now.
