I will be.
I got the iPhone 2G in 2007. That lasted me until 2010.
Then I got the iPhone 4 in 2010, and that lasted me until 2012.
Then I went for the Samsung Galaxy S2 Skyrocket in April 2012. It only lasted me until about February this year. The camera lens dented, and then when I was going to actually go and replace the part, I found out that all my screws had been stripped. So much for buying a refurbished device.
And so now I have a GoPhone by Huawei that I bought in April. But like all cheap things go, I don't expect this to last me that long. It did survive a waterfall of water from a carport though, so we'll see.
I cannot deal with getting a new device every year, or even every 6 months. I buy Apple computers for that reason to begin with. I've actually just moved the iMac G4 into my room so I can give it a new life with a fresh install of Leopard while my parents enjoy my PowerMac G5 after finally getting rid of our aging HP desktop - The only Windows based machine we had still up and running.
This next time around, I'm going to try really, really hard to keep my iPhone for more than three years. And considering I don't do much these days in terms of walking around everywhere with it in my pocket, I hope it's going to be easier this time around.
The only Android device I have any trust in at the moment is the Kindle Fire. My old 1st gen is going to be two years old now and my dad is really enjoying it. My brother really likes his HD too. Those are devices that I think have the best build quality out of all of them in the market right now. They might not be the best, but they are more sustainable than say the Nexus 7 which has bits that will eventually come apart and the Samsung Note tablets which are just plastic junk.
