I wasn't sure, as to tell the truth I wasn't sure whether Legacy just meant old, or was a type of port or something, but judging by the definition NetLingo.com gives, Legacy Systems are:
"An old or outdated computer system that remains in use even after more modern technology has been installed, usually because a company has invested considerable time and money into it and it still holds valuable data. A legacy system may also be an entrenched data management platform that contains proprietary, custom-designed software. Fortunately, new software products are designed to work with legacy systems (or at least to import data from them)."
So I guess it's just a term for old software.
A quick look at Media100, and they're not currently selling Media100i anymore, so I guess we can call it legacy.
I guess what needs to happen mainly, is to shift the "announced products" to the "current products" bit....
