2005 wasn't that long ago, was it?
[[Actually if it had had the 5MP iPhone 4 camera, (which is probably what he assumed since I assumed it too until I looked at the tech specs) he would not have been joking, that could replace a P&S for most people.]]
You don't understand the difference between "better than" and "willing to settle for."
People who are replacing their digital cameras for the iPhone 4 camera are not doing so because it is better than their point and shoot. It's not. They're giving up a number of features they don't understand, don't know how to work, or don't find important for a single button, slower operation, and lower image quality.
Are these studies the follow-ups mentioned here?
My main machine is a P4 1.6Ghz with 2GB of RAM running XP. I did upgrade the video card a year or two ago with something that has a whole 128MB of RAM on it.
4 IDE drives, USB 2.0 (just "full speed" not "high-speed") and an external firewire 400 drive with a flaky controller makes for a...well, sluggish computing experience.
Lately, I've started to give up on it for any sort of heavy lifting (Adobe Lightroom). I started looking at building a new one again, but pretty much have figured out that Dell can do all the work for me for the same money. (for what I can spend)
