I didn't see much written about this, so here's my experience for others considering the Microsoft Surface Book 2 (SB2) for Logos 7 use.
Having just graduated seminary and received some gifts, I decided I wanted to invest in a machine that would serve me well in ministry. Looking at the recommended specifications for Logos 7, I saw that the SB2 meets those (high!) suggestions, and I really liked the look, feel and functionality of it.
My thinking was that I wanted to be able to use the tablet mode (detached from the keyboard) with the split screen - a pdf doc with the Greek or Hebrew text on one side, for me to annotate with a pen stylus as I translate and make exegetical remarks, and Logos on the other side with BHS/UBS open, along with lexicon, grammars, and a few commentaries.
The performance was not as good as I expected. On moving between different resources in Logos there would some times be a delay of maybe 6 seconds. This was a little frustrating. The pdf annotation was a little slow to load my annotations as I scrolled around, but was not a big issue. I tried various pdf programs but all had the same effect, though different functionality.
It turns out that the problem with the SB2 was that when the screen is detached it uses the integrated graphics processor (GPU) rather than the dedicated Nvidia one, because the Nvidia one is located on the keyboard section of the device. Thinking I might be able to manage with this slow performance while in tablet mode, and switch to laptop mode for my more intensive work in the office I persisted. With some tech support I was able to configure the device to use the Nvidia GPU for Logos. However, this had side effects which meant that I was unable to detach the screen for tablet mode because programs were running that wanted to use the Nvidia GPU on the keyboard section.
I contemplated staying with the machine, nice as it is, but it really doesn't work for the way I want to use it. You could elect to not use the Nvidia GPU to avoid the screen detachment issues, but then your performance is limited and you face those 5 or 6 second delays between Logos resources.
In the end I landed with a Dell XPS 15 9575. It has none of the problems mentioned above. The screen does not detach, but you can fold it over backwards, giving you a tablet feel - with the ability to work on it split screen with a pen for annotations. I also note, that despite very similar specs, the i7 8th gen processor is operating at 3.1 GHz, as opposed to the 2.1 GHz that the SB2 reached.
I hope this helps you if you are looking at a new Logos 7 compatible machine.
