From what I see in those pics, even the 2014 Pro version has an inferior LOOK to the Cool one avast had before switching to the regression big time current LOOK.
It could be argued that what matters is how it works. However, having a Cooler LOOK than the competition could be the difference between gaining new customers ... or losing them to the competition.
Potential new customers could be there studying, scrutinizing the Info, specs, capabilities of several Anti-Viruses. If after that the various contenders end up in somewhat of a dead heat, the difference COULD come down to which has a Cooler LOOK. Why not cover that base?
I know of what I speak. After a couple of years of using Foxit Reader as my preferred PDF Reader, I dumped it after they dared switch to that Back to the Past, Low Tech, Childish LOOK. You know ... since PDF-XChange Viewer was equally capable and had a much better LOOK.
So yeah, I think avast is not maximizing their potential by leaving that base uncovered.
