hey, you can try it out for free for 15 days, ive just installed it and been playing with it, as i dont have mobileme, this seems like a way cheaper option..
tried out the gps location thing, and it works pretty well, shows you on a google map and stuff. you can also do remote wipe, pop up a message etc.
one cool thing is when you change your phone's status to lost, it can lock so the thief cant unlock it.. and also disable the power off button, so you have more chance of the phone being on and being able to track it and pop up messages.
the backup function wasnt working that well as far as i can tell though. it can backup to cylay servers and google docs, but couldnt see the backup zip on the cylay site, and only the calenders got synced to google calender.
some of the other settings im not sure about as the wording is a bit weird in some cases!..
