Not difficult. Just a bit of a learning curve (and possibly a bit more time consuming).
The Kindle Publishing Guidelines
gives several examples of how to use media queries to target the two different formats using the same source code.
Judicious use of media queries in conjunction with the "display:none" CSS attribute can be used to tailor the look of both formats (as well as ePub if done properly). I tend to use entirely different stylesheets for each format and then import the correct one using the special media-queries provided by Amazon -- the fourth method described in the Publishing Guidelines (section 8).
