Exporting connection lines to powerpoint goes wrong?

Question

The title says it all, in fact. I see two issues
- when the connection line is a curve, the export turns it into a line
- the end points of the generated line match the center of the shapes instead of the border as in keynote. In case the connection line is an arrow (which is often the case), just rearranging the order does not help.
Exporting to, say, PDF, works fine.
In short: exporting keynote with connection lines to powerpoint does not work.
Any way to get around this (except for not using connection lines)?
I use the latest version of keynote; in fact, it is demo version, I am evaluating whether I would buy it. This issue may be a deal breaker:-(

I understand you don't own any Microsoft products, but have you also stated that "but the presentation MUST be given in PowerPoint" which I thought meant that at some point you have access to a computer which does have PowerPoint, even if it's only a few minutes before the presentation. I apologize for the assumption.
The point being made is that Keynote is not a substitute for PowerPoint if your final output is going to be PowerPoint. If you have not opened the file in PowerPoint, then you don't know what it will look like in PowerPoint. As Tulse has posted, there are free alternatives to PowerPoint that would be better than using Keynote. BUT the same caveat still stands.
I love using Keynote, have used it since it was first released and, enjoy the freedom to create the interface gives me. However, the right tool for the job is sometimes PowerPoint.
