It is more of a chore to read "Conx" I did get it, but I had to do a double take. The third one is better.
I think it is an optical illusion (or either I have been looking at a computer screen too long) but the descender of the p seems slightly angled outward. I know its not, but my eye thinks it is.
Also, seems to me that the pc icon doesn't match the style of the text.
Great job overall.

PS - The optical illusion I am experiencing is with the icon, not the typography. I really like it though. good job.
