That annoying ugly "button" in the middle of the keyboard is the main thing that makes me rule out lenovo laptops in general before I even look at them.
I find it very hard to understand why anyone would want to add one!
I find it interesting that your criteria for selecting a laptop seem to be primarily aesthetic.
I would guess that you are in a small minority here on HN, with most people selecting based on price, feature-set, and possibly brand loyalty/aversion (i.e. "Never buying an Acer again!"). Even if they don't use the nib personally, it's quick to disable and then it's just a visual feature on the keyboard.
Not OP, but I did give it a chance (couple of weeks) and I just can't seem to get used to it. I have no issue with alternative input types (I frequently switch between anything in mouse keys, trackpad, regular mouse and both finger and thumb operated trackballs), but I was just super inaccurate with the Trackpoint, the pointer kept flying off all over the screen it for some reason. Tweaking sensitivity/acceleration helped a bit, but not by much.
I can definitely understand the appeal - having a mouse on the home row is pretty damn cool - but damn didn't I have a good experience. Using it for a couple days doesn't mean you'll like it.
Even though a Mac track pad might be the best trackpad out there, a trackpad has always been less than optimal substitute for a separate mouse, but being build in the device and always available made up for that gap in convenience.
For laptops, if the principle agrees with you, a trackpoint is a far superior device to even a separate mouse for almost all uses.
I found the Mac trackpad worse than those on other laptops actually - seems to somehow get in my way more and it's push down thing seemed far more annoying than the tap gestures common on other devices. Fortunately that switch is possible on them I believe, just seems like you're giving up a "feature" to change it...
In a world where track points were widely accepted, you could go without the big track pad, and put the keyboard to the edge of the laptop, and not have to reach over a big wrist rest. Alternatively, you could make some much smaller laptops, with regularly sized keyboards (and probably overly wide monitors)
