Has Lenovo done anything to reduce the shine that develops on Thinkpad keys after say 6 months of use? I don't understand why the Thinkpad keys aren't coated with some kind of polymer that would slow down the wear, seeing as one of their main selling points is durability. Even the sexiest Thinkpad starts looking like an old POS when the keys get all greasy/shiny looking from minimal wear. It just looks dirty.
I have a 3 year old HP 2710p where the plastic keys still look brand-spanking new with no trace of oily/greasiness (the palmrest on the HP is a different story, but you can peel the stuff over the palmrest off and then you just get stainless steel). HP coats their Elitebook plastic keys with something called DuraKeys. It works. Lenovo should do the same for their Thinkpads. People who say that the shine is inevitable on all plastic keys are frankly just misinformed.
According to HP's marketing: "In independent testing conducted by Trace Laboratories, HP DuraKeys showed no wear after 250,000 cycles. Competitor notebooks showed significant wear after only 5,000 cycles." Personal experience say they are right.
