Er, why?, I can see why you might want to hold onto some old ones, but why more, I've had mine for over two years, is it a presitige thing, don't they all do the same?, if you worked on a firm, using a computer every day, you'd have to prove it was broken before they'd isssue a new one, & a company I know, won't let you bring in your own, they all have to be the same, don't get me wrong, you're enjoying yourself, but think about later, you won't be in a senior position right away, or are going to start up on your own & have what keyboard you want? lol.
