I had a Lenovo SK-8855 R01 made by NMB and it was pretty good (except too big palm rest, stiff flat F-keys and shiny ABS keycaps). I even liked the new thinkpad chiclet keyboard (including its layout for the most part), but…
Dunno, if they've abandoned NMB, but the keys usually start to stick and make “cracking” noise in about a year, just like old chiconys, only worse. Moreover, the new trackpoints reportedly have the same firmware problem as some old ones (like SK-8835 IME): sometimes they simply don't stop moving the cursor in some direction.
