I think I'd go crazy trying to use a nonstandard layout at the office (which is where I keep and use my good keyboard), a standard layout at home (with the wife/kids), and a whatever layout on my laptop. Regarding those embedded numpads, my Vaio has one, and I hate it due to the offset nature of the keys and because it forces me to use the NumLk button. When working (I type documents a lot, no coding, no gaming), I need to efficiently and accurately enter numbers into sentences, tables, or cells from time to time, and I'm not sure if I could live with changing modes all the time. Same with those mini keyboards that use arrow keys combined with other keys. I'm always using the arrow keys to fly around my documents. Meh.
