Hello, if you're using windows 10, linux subsystem is the way to go. I use that all the time for ssh into other servers. Another option is sigwin, but I don't use that at all. HTH.

I myself use teraterm for that, but win 10 ssh client and putty work also very well.
You can do many things with your pi, such as different electronics stuff and low powered home servers. I myself have experimented with the latter ones. I have two usb harddrives attached to it and OpenVPN installed, so I can access my files everywhere. I also used to run a web and icecast server on it.

Hi.
I use my Raspberry Pi all the time.
You can either use Wi-Fi or Ethernet, it's up to you. As for SSH, I use PuTTY.
Just a heads up though, when you plug it in, there is no audio indication to let you know it's on.

I'd recommend using an ethernet cable especially if you're going to be running a headless installation. I don't know of any good GUIs with speech. I can't figure out how to burn the Jenux image to an SD card and Raspbian doesn't have a screen reader. I think Raspbian Lite will work, but you'll need to use ethernet and enable SSH before booting for the first time. From what I've read, you have to place a file called ssh into the root of the fat32 partition of the SD card after creating it.
