On the web I'm known as RGB, RGB-es or el pingüino tolkiano (the Tolkian Penguin). I write, mostly in Spanish but also in English and Italian, about free software, text processing and typography.
I'm the author of a CC licensed book that explains how to use LibreOffice Writer (and talks a bit about Math, Draw and Chart). Originally written in Spanish as Domando al escritor (Taming the Writer), there is an old Italian translation, and a shiny English edition: To Tame a Writer.
I'm also the author of a book about LyX, LaTeX, XeTeX and OpenType. The original Spanish edition is LyX, la otra forma de escribir, but it has been translated into English as LyX, The Other Way of Writing.
Meanwhile I keep writing in my blogs, mainly about free software but also about science, education, photography... whatever I can think of.

For this kind of hardware, there is no real price difference and, for me at least, there is a huge added value on the product of companies such as Tuxedo. Sure, there are "budget systems" for half the price, but the hardware they offer is quite limited, not to mention soldered memories, bad batteries and other not so nice stuff.
KDE's Spectacle: it works out of the box on Plasma, it can take the whole desktop, the current screen, a window, a particular region, share the image on a number of services or just send the capture to any program to process it.
