Why OpenOffice.org Failed - and What to Do About It (ComputerWorld UK)

I have two PCs that are fairly similar in hardware - both are Core 2 Duo with SATA disks, 2GB+ of RAM, 2 GHz or more. One runs Linux and OpenOffice, the other Windows XP and Office 2007.

I just tested Word 2007 'cold startup' (i.e. first time since boot) and it took 11 seconds. I'm fairly sure this is no faster than OO Writer 2.4 on Ubuntu Gutsy, and it feels slower, but I can't test it right now. Office 2003 was a bit faster than 2007 I think, and generally 2007 feels quite a bit slower

The Windows PC as a whole pauses several times a day, refusing to echo typing or even move the mouse for a few seconds. Generally applications on Linux such as Firefox feel much snappier, and I almost never get pauses in echo/mouse movement.
