Not that I think Office matters one iota for a format which is never going to be more than a bad laptop ...there were apparently updates to both the os and office that fixes some performance issues. One of the reviews out there mentions that office is only a preview and not final shipping software . So i guess depending on when the reviews are done could determine performance issues.
I think this clearly shows Microsoft made a huge mistake by spurning Intel though ... Intel is never shy about backing the underdog if it's in their interest, Apple's increasing dominance is very much not in their interest. I think Microsoft could have gotten a great deal and a great x86 processor if they had partnered with them for this launch, Intel would have bumped up the priority of Atom a bit ... now they'll just increase support for Android instead.
