Hi, Steve, consider 'Das Keyboard' or its clone. I know one guy that uses something similar to this and it looks absolutely amazing when I watch him.

There are no letters, therefore it will not wear out.
And by the way, how do you handle going late to bed at 2AM, getting up with kids and starting work at 7:30 AM? I can do it for 2-3 days in a row but later my effectiveness drops to 30-40%.
I was thinking of that. I mostly touch type anyway. Just have to think about some of the symbol keys that I don't use so much.
