Well I finally submitted to peer pressure and opened an
Prezi for education account. I tried to rebuild one of my 'Advanced'
PowerPoint presentations within the Prezi frames and it didn't 'do it for me'. Then I discovered this
blog which explains my thoughts well.

I like new technology, but we shouldn't use just because others rave about it, we should use it because it suits the message we want to deliver. As
Joby states:
For most though, Prezi is not the answer............. use whatever presentation technology you use effectively.
I for one will install the new pptPlex plug-in for PowerPoint from Microsoft and see what effect that has. Will I continue with Prezi?.... I will let you know after I have played with ppt a bit more.
(Bill is my cheque in the post?)
p.s. as someone who experiences motion sickness, poorly constructed Prezi means....[insert you own visualisation here]. Shawn presents
Organization strategies to reduce motion sickness caused by Prezis
p.p.s I confess I also use
Google Slides, and can presentation via from my Google Drive account on-line if I choose to.
