My son got the Nexus 4 this past summer and then read about the glass problems that they had with earlier models. We did a lot of research and found that it may have been a problem with some models. He's had no problems with his phone and uses it all the time - though I think that he'd like the Nexus 5 out now. I ought a refurb Dell computer in 2008 really cheap. Last March it started BSOD a lot. Spent four hours working on it two days ago and found driver, OS update and hardware problems. I fixed the driver and OS update problems and worked around the hardware problems (two DIMM slots went bad and at least 1 DIMM module was flaky) and it's a great system now. So there are a few lemons out there - this stuff is made by people and people make mistakes from time to time.
