How would you change HP's TouchSmart 2 all-in-one PC?

HP's TouchSmart 2 launched without a whole lot of fanfare, but what you get for $1,299 is pretty unique. The IQ504 / IQ506 all-in-one PCs are one of the first to actually encourage full-on touchscreen use in a PC, with HP urging users to touch their way to computational bliss. Of course, with an unorthodox design such as this, there will always be pundits who feel that this or that should have been done somewhat differently, and if that's you, you've found your sounding board. Are you a little let down by the internals? Yearn for more expandability? Is the screen as responsive as it should be? Get heard, won't you?
