It will come as no news to anyone with an iPhone -- or the significant other of anyone with one -- that this slim, useful device does lots of things well. What it does best, it seems, is make time disappear.

Yesterday, I got my first iPhone. This hand-me-down is from the previous generation, which means it's pretty much the same as the latest version except that it doesn't shoot video.

I'm a believer and even more so because two hours after I got it, I called on it to correct my wrong impression of where the dentist's office was located. In its earliest moments in my hands the iPhone allowed me to not miss an important appointment.

As was the case with my cell phone, I imagine that it won't be long before I wonder how I ever lived without an iPhone.

But this morning as I work to clear out the previous owner's photos, music, apps, mail and the like, and replace them with my own, I've learned that the iPhone is a massive time-suck.

While I'm thrilled that I can check my e-mail, MLB scores, international news, weather, Facebook and other things at the touch of a button, I am conscious of the fact that if I don't tread carefully, I'll be on call 24-7.

But, one thing is for sure, I'm exiting the iTunes app store now so I can move on with my day. Well, right after I answer two e-mails, update my Facebook status and send an instant message.
