I am a Mac user and would like to purchase Logos 4, but I am a little uneasy with it being in the Alpha stage. Also, I am also a little concerned since this software & website really seems geared around the PC. That being said the PC version looks amazing. Based on web info it says I can use the older Logos 1 engine until Logos 4 is finished. However, I am having trouble finding out what features I would get with Logos 1 and any tutorials on how to use it.
Questions:
Can anyone comment on Logos 1 and features? Or point me to some tutorials, articles, screenshots?
How stable and functional is Logos 4? Also, do the PC tutorials apply to the MAC version? I understand there is a bit of a learning curve.
Finally, does anyone know when they will be getting to Beta or Final Release? Are we talking weeks or months? Forgive me for asking this but I have stage 4 cancer and just not sure how long I will be able to wait. 
I am also considering another application, but really like the features in Logos.
I really appreciate any info you can provide.
Thanks!
