I like the portableapps.com stuff because it usually doesn't mess with the registry and allows for a very clean removal.

I 've been running the portable version of LibreOffice for a while.  Sometimes it takes a while to come up.  I'm considering trying the full version.  Anyone notice any performance advantage of one over the other?

 

 

That all depends on how fast your portable flash drive is. Example of fast - Sandisk EXt USB 3 

I have it installed on the local hard disk. no USB involvement.

My Partner of 15 years had never used anything but M$ Office before, and say's Kingsolf is almost the same and just as good
