I am Debian user implementing switch to gNS. I would also like to get new hardware more amenable to free software, and I prefer to purchase Lemote's Yeelong...though I plan to move to a custom desktop system if the Yeelong's capabilities aren't sufficient. My personal computing tasks are limited to

1) Emacs text editing and e-mail 2) texlive 3) text-based web browsing (arxiv.org, wikipedia, some basic math/physics journals) 4) ps/pdf viewing 5) compiling and executing light fortran code 6) gnuplot

Can any Yeelong owner's rate the performance of the machine vis-a-vis criteria 1-6?

Also, are there any reports of working external keyboards?

I can see videos on the Yeeloong with 1 MB RAM. For requirements it should be more than enough. It can even be optimized with an optimized kernel or even changing the desktop environment or even adding RAM.
