My upgrade from v3 Gold to v4 Platinum went smoothly, resources are downloaded and indexed and the program seems to run on my Vista laptop without any discernable problems. However, from my perspective Logos 4 is not an improvement on the previous version with respect to usability. Time may well prove that searching is quicker and more intuitive but using the new interface is frustrating and it seems much less flexible with respect to customization than v3. There are several features regarding the interface that are simply annoying (e.g. when creating collections the screen automatically scrolls back to the top of the resource list when a resource is dragged to the exclude window necessitating a repetitive scroll - drag - scroll routine). Also, Logos 4 no longer allows one to print portions or pages of resources directly from the program. So far I'm not pursuaded that the upgrade was worth the expenditure out of my tight book budget and I won't be uninstalling v3 anytime soon ... I'd encourage folks to wait and see on this one; it may well get better as Logos tweaks and upgrades but right now v3 is a more useable tool.
