Sarabander's edition is definitely a huge credit to it's author: It isn't just a reprint of SICP; The text and it's font has been updated, many of the diagrams have been redone for clarity and the document and footnotes are hyperlinked.
If it's your ambition to follow in the footsteps of others or otherwise just prefer the classic Lisp-haqr experience, you can use a TexInfo version of SICP and have both the text and your REPL in Emacs: http://zv.github.io/note/sicp-in-texinfo
Also, just to pimp my own ride: I put together a SICP guide for new explorers of this great text: https://github.com/zv/SICP-guile
It contains both meta-information about which dialects of Lisps and languages are most suited to SICP, overviews of subchapters, helpful hints for those who are following along at home as well as answers to the exercises in Elisp, Guile scheme & Racket.
Woah, yeah I think this is a solid approach. You can remove all distractions and just work on the one page and focus on only the task at hand rather than worrying about dealing with your own setup and can be accessed anywhere.
