Sorry I wasn't implying that the software I used made me a hacker, that is simply just my profession... I use the term very widely to be someone who codes, pentests, reverses malware or jailbreaks iphones...
Yes, I'm saddened by all the responses here making the basic logical fallacy of affirming the consequent. It seemed perfectly clear to me that you meant that a hacker is going to have some means of finding his stolen laptop rather than that using Prey makes you some kind of hacker. And to the criticism that you are running a product, that's ridiculous as well. Do we all solder our own motherboards? Devout Not-Invente…
Personally, it's not so much using a product, but 1) giving access to a third-party (the Prey server admins) to his laptop and 2) being limited instead of having complete control.
Prey just seems a poor solution if you know what you're doing. For non-computer geeks is excellent, though.
