For those who have used iWork '08, how well does it import Office files? Is it a very involved process? For example, if I have a lot of Office files (Word, mainly), can I easily view them by just double-clicking or do I have to go into iWork and then do an Import process? And, when I asked how well it worked, are most of the features supported? Or do documents often get messed up in terms of formatting? Thanks.
