@RealBlackStuff,
sorry, but I don´t think you have any of the new machines. Because of this, I don´t really think your judgement is fair and based on any experince...
The T440s uses different materials than other and older models. The lid is made by a smooth, slightly rubberized material, but not the classical rubbery stuff of older T-models. The new material does not get as dirty, it is very easy to clean and the corners does not go blank as they do with older T-series. However, it seems to be a bit more easy to scratch.
The TouchPad has a very, very smooth rubberized texture, which just feels great and very nice to Touch. It is a great improvement over the older TouchPads with the bumpy-surface, which was introduced with the T400s, and it also does not wear of over time, since it is made out of glass, not plastic like older models. The issues with "gritty surface" are gone, which older models had (see:
http://forum.thinkpads.com/viewtopic.php?f=18&t=98352). So,
RealBlackStuff, your claim about the discontent is the difference in touchpad texture"
is wrong.
The displaybezel is still normal plastic, very thin. The rest of the T440s is made out of either Magnesium (the base-cover) or plastic with Magnesium directly bonded to it to ensure great stability. Botht the plamrest and the basecover are slightly rubberized, which stops wear from happening. The new materials used are also very easy to clean, unlike the old rubberized material.
The T440s has much better materials and blows away older T models like the T420 in this department. The keyboard does look greasy after some use, but it also does not get glossy (I have the backlight version, the non-backlight keyboard might get glossy).
And about the general critisism on the ergonomics: This is something very personal and subjective. Haveing used and owned T420, R60, T430u and now the T440s, I can only say that the T440s has the best ergonomics. And I am a TrackPoint-only user, TouchPad is always disabled...
