The Singularity may be as much to do with our expectations and impressions of technological advancement as it is about actual advancement. After a few years of owning something new and exciting yourself, you can't imagine your world without it, so it's hard to imagine that anyone else is doing without it. Who among you with an iPhone honestly believes that pretty much every phone out there is an iPhone or at least a big-screen touch phone with many gigabytes of storage? It ain't true. The pace at which you think technology is advancing is closely related to your own contact with it.

PS - The Singularity is kind of when technology outpaces itself.
PPS - Personally I'm not so sure it's going to happen.
