Yeah if you have a document written in LO/OO, that's true however loading still some XLS files is just akward. I mean probably due to the spec and even microsoft sometimes had bugs in their program so that at some things the spec didn't helped. like some table bugs etc. But still I don't wanted to says XYZ is better overall or so. I just wanted to point out that resource usage and loading bigger files is definitly not the thing were office shines at least the newer versions and also don't expect office for mac to be good, it sucks.
