Had read about these things in various places and decided to grab one for the measly $35. Also got a case for it for $7 and a power supply for another $12.

I already had a Dynex USB SD reader to flash the OS but picked up a 64GB Micro SD Card from Wal Mart to flash it to.

I hit the Raspberry site to download Raspbian OS.
Went to Balena Etcher site and downloaded/installed the flashing program.

Connected the Dynex reader w/ 64GB Micro SD plugged in to Windows 10 laptop and ran balenaEtcher from desktop shortcut. Navigated to still zipped Raspbian OS file and the program flashed then verified it to the SD Card.

Installed SD Card in Raspberry Pi, connected it to a TV via an extra HDMI cable I had lying around, powered it up, connected to internet via wifi (which I did not know was included 😀 ), updated the programs via prompts onscreen and now staring at an incredible Linux computer system that's on a device smaller than my hand 8)

Going to update here as I find ways to configure the OS to what I need. This thing is crazy awesome!
