I dunno, my experience has been that pad printing actually lasts a lot longer than its reputation suggests. I find that laser etching with paint starts to show visible fade after only a few days, while pad printed characters can stay nice for months or even years.
Of course, given the price that DAS is charging for this product, I would want to see some kind of USP for it. It's okay by me if it's not the keycaps, since cheap keycaps seldom have any effect on the functionality of the device, but if they're going to go cheap there, I would want there to be some rare advantage elsewhere to make up for it. And I'm not seeing that right now.
