A bit late, I was away.
Actually it's somewhat correct, resistive touchscreens are not very reliable in the long run, they are prone to damages and don't respond well after sometime. But not all phones are like that, Nokia is a company of repute and one expects good quality stuff from them. I have seen my friend using moto rokr for 3 years without problems, one of the first phones without a keypad. So if one uses it with a bit of care it can last long.
However, all this is not a matter at all with capacitive screens, they are very reliable and over all much better to use.
Moro Rokr was one of the coolest phones..I ever used in my life..specially the Custom firmwares/features..I still have it as a brick phone due to my own mistakes !!
