It allows for remote access to your machine and apparently it can even be used to catch a thief. My rough impression is that it seems like it is a lighter version of Apple Remote Destop or VNC.

I don’t usually have a need to remote access my machine that much — it’s a laptop and so if it isn’t with me it is usually just shut off. And if it is off with the lid closed, it ain’t likely going to wake up again (though I’m assuming if it was asleep with a network cable attached, it could?).

That being said, I am starting to not take my laptop with me when I’m out of the office for meetings. It’s heavy and I’m frankly trying to save my lower back. Instead just use my iPhpone. Between Safari, Mail, MobileMe, iCal, Address book, and all the other goodies like OmniFocus on my phone I find I don’t need my laptop unless it’s for something specific (such as a presentation).

Now that I’m leaving it behind more, I now can see some limited need to leave my laptop on and be able to access it from my phone, even if just to access files or to have it as a spam filter.

Anyone have any suggestions or further thoughts?
