I've owned an NC10 since early December. Only three complaints, all livable. The first is the touchpad/clickers. Agreed, the pad is too small. I don't agree it could not have been made (even a little) bigger. Seems there could be another 10-20% they could've squeaked out. The left and right clickers should also have been designed as separate pieces. This issue, however, is solved with a wireless mouse; and the mini-dongled Logitech I bought is about perfect.
The second issue is build quality. It's really not bad at all, but, with a couple of very small changes, the NC10 would come off much better. The outside surface of the lid/screen could be tied down a bit better near the hinge side. It flexes when you pick it up leaving a less-than-solid impression. Mold another attach point, or two, and that's done. The next is the execution of the chrome around the side. Upon closer inspection, it looks cheap. It's more fit, than finish.
And, lastly, the edge where you place your wrists (while gleefully touch-typing) could be more rounded for a more modern look, as well as better comfort.
The NC10 is so good otherwise, these things actually rise to the level of an issue. Great battery life, great keyboard, excellent storage, speedy enough (specially with 2GB) and very accommodating to a lifestyle of mobility and travel. No regrets after over two months of daily use.
