The biggest problem with OpenOffice, other than the fact that most corporates won't adopt something they're not familiar with or that will require additional training/resources (one of the mentions was that Nokia's happy about this because it allows them a full business suite to compete with RIM) is the fact that it's always been rediculously bloated for what it is. I mean, it's on par with MS office in terms of foot print and memory usage on desktops, and quite frankly, an open source app SHOULD be able to be much smaller and more efficient than that for the functionality that's being provided... but my guess is this is just more about MS being afraid of loosing ground to Google/et al than anything else. After all I hear rumours of Chrome OS knocking at MS's holy grail...
