So, it's a bad laptop in my book (pun not intended).
You see, a laptop needs a good keyboard; and a good keyboard needs height for the keys to travel. So, a laptop needs to be kind of "think as a brick". Maybe not at 2005 levels, but definitely at 2010 levels and no thinner.
However - a laptop which is reasonably easy to disassemble, and hence customize, is definitely something I support in principle. I'm not sure this can catch on if it's essentially a single-vendor thing.
