I've been using this virtual keyboard since version 3.3 and I have absolutely no complaints. As a quadriplegic, without the use of my hands, I was extremely disappointed when I purchased my Mac, to find out that the virtual keyboard that comes with the OS X operating system, doesn't work.

Almost immediately, I found this virtual keyboard and I was definitely impressed with its functionality and ease-of-use. While version 3.3 may not have been as visually appealing as say the Windows version of virtual keyboard, version 3.8.4 definitely makes up for that with the 3-D feature, as well as the new minimize feature. I was glad that the upgrade was free for registered users but, I would have gladly paid for this software again.
