Thanks for responding, I'll try to clarify a bit:
When I was younger, I couldn't pull myself away from video games and PDAs. Now, it's the latest smartphone, computer, Internet connectivity device ... Even if I don't have the device and have no intention of purchasing one, I'll spend hours at a time on the Internet studying how it works and potential usages. And by hours, I mean sometimes up to 2AM or later. (And if I do own it, I may spend hours and/or days fiddling around with it.)
I should probably add that spending time 'surfing the Internet' falls into a similar category for me - I'll spend lots of time just looking for something interesting that I can learn about next.
