>IMO this doesn’t seem disrespectful, more like an attempt at authenticity. For those who used computers at that time, it will remind them of what it was like, and for younger people, it helps communicate the era (before you were born, but post-GUI) that 9/11 happened in.
I mostly agree with you. However, I visited Las Vegas and stayed at the New York, New York casino hotel a few months after the towers came down and noted the "memorials" people put up on the outside of the casino. Which, as a native NYer who worked across the street from the WTC (and walked through it pretty much every work day for many years beyond that) for more than three years, really pissed me off even though I realized that people wanted to show their support -- I found it a disgusting display.
I still live in NYC and to this day I avoid the area around ground zero whenever I can. Not because I'm afraid, but because it's still painful to think about all those dead people in a place that was so familiar to me.
As such, I understand GP's feelings. The events of that day shouldn't be made light of given all the innocent people (and not just in NYC, but in Washington, DC and Shanksville, PA as well) who died needlessly. And each of us processes/deals with that differently.
