I just noticed that a a little bit of the silk screen on a few of my buttons has partially worn off already - not a lot but enough that I noticed it. Especially on the down arrow of the 4-way (or is it 5-way?) navigation button. It's a bit worrisome I've only had mine for a few weeks, and with only 1-2 hours use per day this is happening...
Has anyone else see this on their K3? How do previous Kindles' keys fare over time (K1 and K2)?
It's too bad that the K3 button legends appear to only be silk screened on the keys and are not embossed with the letter/symbol.
