You're right though, that really was a useless (and ilinformed) comment.
Windows 7 is the first OS produced by Microsoft to even hold a candle to Mac OS - and IMHO has outdone it (which is saying something). XP, however, is fairly universally (outside of your house) accepted to be one of the worst, most buggy, unstable and least secure operating systems of all time.
I have a feeling the upgrade path of global enterprise won't grind to a halt because the Garmin Trainer will only run on XP
