Dell certainly managed to cram plenty of inventive, even far-fetched touches into its Adamo XPS laptop, but it looks like it went even further out on a limb during the prototype stage, as PC World was able to discover during a brief hands-on time with a few cast off concepts. As you might expect, one of the ideas Dell toyed around with was a full-fledged touchscreen trackpad, which was apparently rejected because Dell couldn't justify the cost of the panel based how much people would actually use it. Another, possibly even more ambitious concept is one that would have completely replaced the traditional keyboard with a series of capacitive-touch buttons (pictured after the break), which would have allowed for a true zero-profile design, albeit at some potential expense to usability. Hit up the link below for a look at a few more prototypes.
