You mean the 'budget' PC-line keyboard?
Got one of them myself. Probably the best £10 I ever spent on my computer. The ASDCNE keys are fairly worn but the keyboard's still going strong. As a result of levering off the Windoze keys and the three Power/Suspend/Wake keys (those six are the most utterly useless keys ever added to the standard QWERTY design) I have six spare keysprings, which should last me 30 or 40 years on current showing.
If I ever replace this keyboard, it'll be for an original Model M.
Re: keyboard with key displays.
It's a gimmick, mostly. I can see how it could be useful for developers using apps with complex key schemes, but if I ever see one at a LAN party I'll know who has the most money to burn.
The indestructible keyboard... a good idea, but is it proof against a Leatherman blade, or a soldering iron? I suspect it handles like a laptop keyboard too; there's a reason why I hate laptop keys.
