What Works for you
Not a Data Centre tale, but I recently had a client come to me to upgrade from desktop to laptop, as her desktop had finally given up the ghost. I advised her on a suitable laptop and undertook to get all her data across, to run under OpenOffice 3. All went well, until it came to her word processor documents, which turned out to be wps files from Works for Windows 3, circa 1995. She had never needed to upgrade before, because the kit she had covered all her needs. Isn't that the way it should be? Change only when what you have doesn't do the job, or could be done more quickly/simply/cheaply?
BTW, converting Works 3 wp files to doc or rtf is not an easy thing, anymore, with very few converters going back before Works 6 (including current MS offerings). In case anybody else has the same problem, you can massage them through Ability Office -- as I eventually discovered.
