Lots of businnessmen and tech geeks are demanding those old Nokia series (3210, 3310, etc) nowadays, since they're reliable and rock-built. A phone that's still working 10-15 years after it was released is a gem and laughs in the face of HTC, iPhones and the likes.
Whilst I agree, I wouldn't replace my smartphone with an old phone. All of my fourth and fifth generation games consoles are still working perfectly fine. Then again, all my consoles are, but RROD is well publicised on Xbox 360 and PS3 have had issues too. The demand n the consoles is a lot greater though. Same with phones, the 3310 was used to call and text, occasionally a game of Snake. Today, I speak for myself and probably the majority, phones are used for everything, from SMS to gaming. And would you really by an iPhone if it was built like a 3310? As long as your careful, you can keep your gadgets in perfect condition. I've managed it.
