How to confuse a salesdroid

Just had a call from BT trying to persuade us to swap to their broadband system. The moments silence on the end of the phone when I replied to her question "do you have a computer?" with "well there's three desktops currently running, one with macOS, one duel booting WinXPpro and Win7 and one paritioned to either start up Windows or Linux. Two lap tops, one running XPpro and one Psion (I forgot the Asus) and there's an Atari in the corner for legacy DTP work." was priceless.
