ESPIRIDION  I somewhat agree regarding the different versions and names.

On a positive note, they do have a Survey and will recommend a specific version based on customers' needs.

They also provide a phone number.

It would be nice to just have a simple table highlighting the features and differences across versions.

I've only used it briefly so I don't have an informed opinion. I will post a more thorough review at a later date.

IANWEIR  I'm interested to know if the next version will be AceReader Pro Deluxe Plus Super Ultra Mega-Platinum Ultimate Extreme.

Surely the names of this suite of programs could be simplified into something that makes a bit more sense and serves to inform rather than confuse, as they do currently.

Looking briefly over your website, I can't find any semblance of a logical pattern to your naming conventions, which as I already stated serves only to confuse your potential customers.

When you need to put descriptions such as "(Single User Home Edition)" and "(Network School Edition)" next to the product names, and even include a survey so that customers can figure out which version they're after, it's a pretty clear warning bell that you've made things a bit too complicated.

I think you should consider these names:

AceReader Home (formerly AceReader Pro)

AceReader Home (Multi-User) (formerly AceReader Pro Deluxe)

AceReader School (formerly AceReader Pro Deluxe Plus)

AceReader School (Multi-User)/(Network) (formerly AceReader Pro Deluxe Network)

This way your potential customers understand the differences without having to consult a chart, and you don't get caught up in the excessive and needless descriptives that really only take away from the name and brand.
