one more thing I like about Linux... is DOS Box ..If there is an old DOS game you still like , chances are very good you can get it running in DOS box. Sure there is a version for windows7 bit the Linux version is more stable than dos ever was. And all the games are on abandonia for free down load..
like the original Civilization or empire deluxe .. it is out there ..
or are you a leisure suit Larry fan?
all with a few clicks and free downloads...
not sure of the MAC version... probably pretty good speed on an Intel chip...

get that dead PC going with a new OS , and a new life
or craig's list it so some else can...
