I have it... I wish they'd offer a MobileMe Lite service with significantly less space and no e-mail for a substantially lower price, because there are free services for e-mail, photo galleries and online file storage/sharing (e.g. DropBox). I very rarely sync my iPhone with my computer, so it's nice to be able to sync stuff over the air. I don't use my laptop outside of my house ever, but if I did I think I could see the usefulness of the file storage.
