I would say my original Droid lasted for the longest time, and replacements fail daily. Original Droid: 8 months (Touch screen no longer responsive) 1st Replacement: 1 month 4 days (Too mane dead pixels) 2nd Replacement: 1 month 1 week (Volume up key no longer functioned) 3rd Replacement: Just got it yesterday. I am assuming replacement will last about a month as well. The worst part is each Droid I get, I customize less and less because I feel as though it isn't worth the time know I will just have to send it back eventually anyways. So how long have your Droid replacements lasted?
