Have Keyboards Gone Crazy?

Ethelthefrog asks: "My office keyboard recently failed and I am attempting to choose a replacement. Unfortunately, Logitech, who make keyboards with an action I really like, seem to have gone crazy. They have trademarked their worst features: Zero Degree Tilt(tm) means I have to reach uncomfortably far for the number keys and their horrific 'Enhanced Function Keys' means I now need to engage a shift-lock type function just to get at F1-F12. Are there any geek-friendly keyboards out there that combine decent action with just the keys I need to hack and no more?"
