I needed a particular software utility (a hard disk partition archiving program). I was in the middle of some other work on my machine running the Debian "testing" distribution. I didn't want to interrupt my other work, but I had a few minutes to download and burn the needed software to a bootable CD.
I hadn't used Debian to burn a CD before, so I worried was going to demand I use various command line arguments with the usual reading of manuals. I was wrong.
I found the ISO image (thanks google), downloaded it with the web browser, clicked "open" from the web browser, and it offered to open it in "brasero". I inserted a CD-R in the CD drive, and brasero happily burned that CD with no complaints.
Thanks to the open source community! That was a great experience, simple, elegant, and did what I expected.
