I recently received my copy of the 2016 text edition of the ESV Personal Size Study Bible in the Portfolio/Walnut Trutone design. This Bible came in perfect condition and is exactly what I was looking for to replace my "standard size" ESV Portfolio/Walnut design study Bible--for increased portability.
I love many attributes of this Bible: lays flat (after using it for a bit, doesn't take much for it to lay flat), black letter text, size 7.7pt font is very readable in a single column layout (I would recommend Crossway's other Study Bibles with larger font if small font is a problem for you), ribbon marker, and much more!
I am definitely a fan of Crossway's Trutone bindings, but have been spoiled with some of their higher end bindings recently (top grain leather and goatskins). With that said--I would still HIGHLY recommend their trutone leather and not let that deter you from purchasing this Bible.
I also have a friend that is very happy with the cloth over board w/ royal imprint version of this ESV personal size study Bible. I would recommend that one as well.
Lastly, the 2016 text addition seemed to have re-added the extra articles that Crossway's standard size study bible has--I believe the 2011 versions removed this to save on size.
You will be getting a lot more than a Bible with cross references with this Bible--you will get a TON of commentary and bonus articles/theology.
Lastly, it is still somewhat big for being a personal size, but compared to other personal size study bibles of other translations, it is definitely in line with a typical "personal" size study Bible.
