Vista Bitlocker
A while back, I said that my dream job at Microsoft would be to refuse dumb product names.
"WindowsCE?" I would say, "You do realise everyone will call that 'WinCE', which is something you do when you're in pain, yes?"
".NET Server? What does the OS have to do with .NET? Is it based on .NET? Do you have to run only .NET apps on it? Is its primary purpose to run .NET apps? Then it's not a '.NET Server' - go rename it." Okay, so someone else already fought that battle and won.
Today's example of "I wouldn't have called it that" is Vista's whole-drive encryption scheme, "Bitlocker". The most polite spoonerism of the word is "Bootlicker".
Don't ever name a product so that it can be accidentally mispronounced in a funny or rude way.
Which brings me to the name "Vista" itself...
