The Palm can do quite a bit more than simple business crap too, don't let the small system specs fool you. The programs are writting stable, compact, and use little or next to no resources much like the Amiga of yesterday before the days of M$ bloatware came into play. My friend had a Palm and even watched videos on it.
Regardless, I can see someone wanting to have a virtual Palm on there TV, if not to communicate with a real one, to at least have the good library of apps available, if not for some of the games. I think there is infact a "verson" of Serious Sam for Palm.
