More information about TeXtures?

I'm a relative newbie to both the Mac and TeX, having switched (from 
Windows and Framemaker) about a year ago. From time to time, I've seen 
people refer wistfully to TeXtures on this list. I've gone to the 
Bluesky web site to find out more about this program, but they 
(surprisingly) give very little information about what seems to be 
their flagship product. I'm wondering if someone can fill me in on what 
the main advantages and disadvantages of TeXtures were, and, if anyone 
knows, why it has not been updated for OS X. Thanks!
