what are some amazing things i can do with icloud with my setup(ipt4 and macbook lion) ? i purposely stayed away from any ios5 news and now i'm confused. the only thing i've been able to sync so far in the cloud has been ical. what are some other nice things I can do? is there a folder I can put files to on my mac to be automatically send to my ipod touch(similar to dropbox) and vice - versa ?
