ZoomText is a powerful program with many great features, BUT think twice before investing the money. AI Squared sells primarily to government organizations purchasing items for clients. We all know what happens in industries where government funds are the primary sources of revenue. Companies become arrogant and overpriced.
For example, in addition to ZoomText's excessive price, they offer little or no support between operating systems. I have owned 3 versions of ZoomText. Every time I upgrade my operating system, I have to BUY the new version (or the "upgrade" to a new version) for my ZoomText. AI Squared produces a new version of its product every time Windows produces a new operating system, and the old version WILL NOT work on a new operating system. That's right, it is not backwards compatible--built in obsolescence. Programmers could simply produce a patch for the new operating system, but instead the company takes the opportunity to fleece customers out of $200 to $300 (used to be more). The company just assumes that most customers will use a government program and funding to buy the upgrade; so, it doesn't bother them that many clients can't afford the upgrade.
Windows and OSX now offers many of the same features offered by ZoomText including magnification, reading, and even converting text to audio files--if you own recent versions you have these features for free. But even if you don't, instead of spending the money on ZoomText, with just a little more money, you can actually buy a Mac which offers features superior to ZoomText embedded in the OS. So, instead of investing into this cycle, just through a few more dollars into the computer and the accessibility features you need, without the constant expensive upgrades.
