I read all the reviews, but not ONE mentioned the fact that the update software was incompatible with Windows Vista or 7 64 bit operating systems. Whats more, this has been a known issue since 2008 and Celestron has posted no warning in their literature! There is no way to update the goodies for the gadget! I'll be returning mine ASAP. They obviously have a "we don't care we don't have to" apparoach to customer service.
Pros: easy to setup, good features, excellent idea
Cons: software doesn't work with a lot of windows OS's
