NIKON D70 UPDATE: As I mentioned a while back, sent the D70 back to Nikon for a minor but annoying problem. It came back yesterday, and now seems to be working fine, though the problem is intermittent enough that it’ll be a while before I’m completely sure. They were pretty quick, and the process was painless enough.
Meanwhile, the Dell has the same screen-flicker problem noted here. It’s rare, and rebooting seems to solve it, but I could live without it. Otherwise, I remain quite happy.
