Versatility vs sanity

My motherboard is aging
And yet it's still precise
Computing, searching, waging
An intelligent device.

It's the hardware that is failing
The keyboard's in a funk
S is on the railing
And A is in the the trunk.

My fingers find it fascinating
It keeps my brain quite sharp
Searching for the vacillating
Keys that never park.

SharpKeys has been a boon
Computers cost a lot
But I can see that soon
This all has got to stop.
