iPod Deathclock: Upper or downer?

The iPod Deathclock is a website which, after inputting your iPod serial number and usage patterns, purports to use some fancy math to determine just how long your musical buddy will live. The accuracy of something like this is, from an engineering standpoint, probably horrible. But for a user, it's a date that will enter the mind and most likely never leave.

The question is whether this quantification of the iPod's mortality is a bummer or a pick-me-up. It could be a bummer because, hey, you just dropped hundreds of bucks on this thing, and it'll only last until then? On the other hand, it could be a date to look forward to, because on that date you'll have to upgrade to the shiniest new one on the market. The perception of the quality of the iPod itself is also affected, seeming either to be either a junky thing that doesn't last or one of an exciting series of products that will just keep improving.

So, what influences whether a user sees the glass half empty or half full? Is it related to income? Tech-savviness? Natural optimism or pessimism? Apple or Microsoft fan?? It'd be fascinating to know, but we probably never will...
