Is there a reason to use this over LibreOffice? I had until this year a pretty old machine (~11-12 years old at time of replacement, upper midrange at time of purchase) and I never felt like it was slow -- possibly because everything was slow on that machine though and I was stuck in a forest...
LibreOffice definitely feels sluggish. I give it a pass because it's doing complicated things, it's free software and I also temper my expectations slightly because it's a Java GUI application (and I expect those to be slow). I would certainly not expect it to be more performant than Office '97.
It would be great if LibreOffice had a spurt of speed-ups. Kind what the browser wars also competed fiercely about.
