Great work on the Alpha! I am starting up my Window partition (via Fusion) less and less. I still use BibleWorks for morph searches - more because I know how to get around that one quick and have HALOT and Waltke/O'Connor on that platform (a cross grade pricing would be nice, ANOTHER company offers such a thing....)
Anyway, I am finding L4 to meet my current needs. This includes class prep for teaching 100 level Pentateuch and Synoptic Gospels courses. In addition I have been able to purchase some great resources related to my Master's thesis (Discourse Linguistic and Narrative Critical analysis of Exodus 2-4) through Logos that would not be possible otherwise. It's great to see many JSOT Supplement volumes available for a good price. Getting those things in hard copy is difficult and costly.
Anyway. Just saying thanks for all the work and the great thinking with the Alpha process. I'm sure that with a variety of users testing and using the Alpha's and sending in reports we're going to see this move way quicker than if it was all done in house.
