Just in case anyone has a similar setup, I thought I would share my experience upgrading to L5.
My L4 configuration:
- Bible Study base package
- Moderate number of Logos resources bought outside of packages.
- Moderate number of 3rd party resources (I think irrelevant to Logos upgrading)
- Obtained the following L3 add-ins (prior to them being withdrawn for separate sale sometime during Summer, 2012; they are no longer available):
- Bible Analysis Add-in
- Compare Parallel Bible Versions Add-in
- Sermon File Add-in (a promotional freebie in '08)
- See this thread for more info on L3 add-ins & L4 lower-level base packages. But remember, this is relevant only if you had purchased the L3 add-ins prior to their withdrawal for sale or had them in L3; their functionality is no longer sold separately.
I side-graded to the L5 Starter package; my upgrade price was around $50. This gave me:
- The L5 environment with the new non-package-dependent features
- A number of new resources (that number will be different for others, of course)
- The Events part of the Bible Facts (People, Places, Things might be improved, but were in L4)
- The legacy L3 Bible Analysis Add-in brought the Passage Analysis Tool in L5
- The legacy L3 Compare Parallel Bible Versions add-in brought the Show Differences and Show Base Text features into L5 Text Comparison, and it brought the Pericope Sets Database into L5 (I think), where it is used in the Home Page passage box and in the Text Comparison reference box (and maybe elsewhere; not sure)
- EDIT: The legacy L3 Sermon File add-in brought the L5 Sermon Starter Guide.
So, even if the coming crossgrade is a better deal, Robertson's Word Pictures alone is worth close to my upgrade price.
I hope this helps someone in a similar situation and isn't another cause for confusion.
Also, my laptop's specs are below and, so far, L5 seems to work as well as L4 (I'm not much of a poweruser).
