I have been using Logos-4 for about 3 weeks for study and for PowerPoint slide production. Now, I have had enough. I have gone back to Logos-3. Logos-4 is much slower, is user-unfriendly, cannot do some things that I depend on, and does not do some things I depend as well as Logos-3.
Some examples:
1) start up time -- to load and get to reading a desired Bible verse takes about 2 times as long in Logos-4
2) search time -- time from hitting Return to seeing the verses takes twice as long in Logos-4
3) typing in "book chapter:verse" -- often Logos-4 is doing something else in the background, so the feedback is sluggish
3) copy/paste verses from Logos to PowerPoint -- Logos 4 has a mind of its own. Sometimes the entry of the verse selection into the copy frame does not update the selected verses; Copy/Paste to PowerPoint always creates a new slide; Copy and then goto PowerPoint and Paste does not pick up the style of the selected paste-to area, i.e. while creating a slide, copy and then paste does replace any selected text, but it changes the formatting -- creating extra work to fix the formatting.
4) copy verse list -- cannot do in Logos 4 (feature remove that worked fine in Logos 3)
I write this with the knowledge that I will be told I need to upgrade to a Quad-Core i7 to run all these features I never knew I needed.
