Apple received significant criticism upon the initial launch of MobileMe last summer due to numerous issues that ultimately led to an acknowledgement of the problems from Steve Jobs and multiple free extensions of service to affected users. While Apple was able to work through its early issues, it has also continued to tweak performance and add features to the service.
