Microsoft Silverlight told me to buy a new mac

A site my wife needs for work recently overhauled their site using Microsoft Silverlight (didn’t say “upgraded”). My wife’s iBook G4 works perfectly for streaming video, email, calendar, and basically everything else a personal trainer would use.  Unfortunately, Microsoft decided the new version of Microsoft Silverlight should not support G4 macs.

It sounds to me like Microsoft Silverlight is telling me to buy a new mac, which I did.
