Logos 4.0b is awesome. It is so much fun to use that it was difficult to pull myself away from my computer last night and go to bed (Fortunately, I had my iPod touch to read in bed and slowly wean me away from the computer).
A15 is very good too. I use it during the day when I do some of my studying at The Grind
. But I keep thinking, "Man, those Mac guys have their work cut out for them" (to keep up with the PC development). Keep pressing on "Mac guys", and thank you for the product you have given us thus far!
