Silicon Valley Insider has a clever list of 21 things that became obsolete in the last decade, including a sometimes-interesting discussion of which of these are really obsolete (Is the land line gone? Chez Buce still has a land line, but why?)
One item I didn't notice on the list: the flash drive. I bought two the day before I discovered My Dropbox. Oh, and later Evernote.
And here's a candidate for shortest lifespan: installed dashboard GPS. Mrs. B got one on her new Toyota in 2004; we thought it was cool. Seems like two blinks of an eye and everybody had one on their pocket gadget.
[H/T: Carpe Diem.]
Update: Okay, so I open my Sunday paper this morning and there's a huge ad showcasing the dashboard GPS on the Cadillac Escalade. Does this mean I am behind the curve? Or they?
