We had already installed Microsoft Office Professional Plus 2007 Beta 2 moment ago and seems like the floating graphic is the heaviest workout. Our system is running on Pentium 4 2.8Ghz HT with 1.5Gb of RAM and still it slow down while opening office program. We like the simplex design pretty much and its completely different from the previous office version especially the features layout. Would you like to get one?
