My test PowerPoint file had some graphics for a
new company organizational chart and all the lines between the boxes
were drawn in the wrong locations.
Designed around a subscription service, ThinkFree office can be
downloaded from http://www.thinkfree.com. I used the offline installer,
which you can download from
http://www.thinkfree.com/login/download_linux.jsp. As a subscription
service, prices are listed at http://www.thinkfree.com/login/login.jsp.
A one-year subscription of the ThinkFree Office Standard Edition costs
$49.95 US. That did not seem unreasonable and comes with 20 MB of
online storage. On the ThinkFree site, you can register for a 30-day
trial subscription and run ThinkFree Office in offline mode 29 times
before you must sign up with their service, but that should be long
enough to give you an idea of whether you want to use the suite.
