I bought my T430 (N1T56PB) on August 2013. 10 months later "Tab" key fell off. 2 months later "A" key fell off and few months ago another one - "S". Currently "E" is the one that behaves a bit differently and surely will be the next one to fall off. At the beginning I thought that these islandish keyboards aren't that bad, but after a year I'm sure they are total crap, which shouldn't be put in stuff that costs $1500+. Previously I owned R61 (NF55WPB), which was surely lower-end laptop and I didn't have any problems with keyboard for 3 years that I spent using it (until NVS140m exhibited its factory problem and I have no longer seen anything on the screen).
