Just an update to my previous post (about 4 back) . . .
A friend found out I was planning to buy one soon and beat me to the punch, early Christmas present!
So I now have my Raspberry Pi. It's a 4B 4GB from CanaKit. Came with heat sinks, an enclosure with a cooling fan, power adapter, power switch (I really like that!), HDMI cable, a card reader, and NOOBS on a 32GB micro SD.
Unfortunately the wired USB keyboard that I'd planned to use turned out to be junk (it was old). A trip to WallyWorld yielded a Logitech wireless keyboard/touchpad combo for ~$20. Back in business.
Assembled everything and set it up with the card from the kit, but I had really wanted to do that myself, so as soon as I had it all updated and working, I pulled that one out and put it aside for safe keeping. I then took the new Sandisk 32GB card that I'd already had set aside for the Pi and went to work. I downloaded "Raspbian Buster with desktop and recommended software" and "Etcher" and created my own card, which I then installed in the Pi. Having already successfully installed NOOBS (despite having to quit and go get a new keyboard) setting up Raspian Buster went smooth, and soon I was online, posting on forums and watching videos.
So soon I'll be bugging you all in the other threads with lot of dumb questions.
