I'm on a one year replacement cycle so bring them on. Ask yourself, what was the best phone 2 years ago? The Iphone 3G and the htc touch pro? These are crappy phones compared to the DX and in 2 years the DX will share the same fate.
I don't think anyone here is delusional enough to think in the summer of 2012 when their contract is up they're going to pass and just keep on truckin with their DX. But 4 months is hardly the time to start panicking that your phone is outdated.
I used to think I'd hate to be a Sport bike designer. Because for all the hard work and effort those guys pour into those bikes to make them top notch performers, packed with ridiculous amounts of technology and able to do astounding feats... two years after it's released they are replaced by an all new, from the ground up version, and suddenly everyone considers the old model slow, clumbsy, and technologically primative. That would drive me mad.
But as fast as that industry turns over, the cell phone industry is light years faster than that even. Gosh I'd hate to have been one of the guys who spent endless hours trying to make the Nexus 1, Incredible, EVO, Droid X or any of the smartphones that came out this summer, as awesome as every one of these devices are in their own right. Only to see kids on the forums a few months later saying, "man I can't wait to upgrade from this POS to something that can do more"... I think I'd go insane.
The ability to please society is getting ever increasingly more difficult with every stride forward we make. I'm really floored at just how amazing these tiny little things really are, all the things they can do, and the posibilities are even more endless with the apps available off of the market... and yet people (and I fully include myself in this scenario, so don't think I'm balking at society, I'm equally at fault for doing this) walk into a showroom floor, pick one up and play with it for 15 seconds, put it back down and say, "man that thing is a piece of crap". Just think if Marty had a Droid X to take back with him in that DeLorean... who cares if he couldn't get a signal, they still would have thought he was Jesus!
Talk about an easily jaded generation. Man it's no wonder the divorce rate is climbing higher and higher in this day and age. Think about your grandfather for a second... he got a baseball glove when he was 13 years old, and that was the only thing he played with until he graduated from college and started a family. Of course he stayed with grandma his whole life, he didn't have 'upgrade' engraved into his brain.
How on earth are our kids supposed to stick with the same guy/gal for 60 years when their insanely awesome cell phone can't keep them content for 6 months?
