You are right, but I guess a lot of people recognise PowerPoint as a brand. Maybe I can bill this as better-than-powerpoint!
replyFactorialPoint, your slideshows improve even faster than an exponential!
replyHehe, if we go in the other direction we can call it basepoint.
replyThe term "powerpoint" has been genericized in the common vernacular to mean any electronic slide show, like kleenex for tissues and sellotape/scotch tape for transparent adhesive tape.
replyIt might not have reached legal generic status but just about any working professional will understand what you mean if you refer to "making a powerpoint deck" even if you don't use the actual Microslop product.
