So, Billy-the-Master-of-the-World can say that the DOS kernel is 16-bits (the Winbug 95 one too, don't forget), non multi-tasking (that's true, but Zindozs isn't really too), and speaking of the 640K limit (he never heard of Protected Mode), the DOS still be the best choice, except, of course, if there is a Linux version of all your programs.
Windaube 95? Vous êtes peut-être masochistes mais moi, je n'utilises un pseudo-systéme d'exploitation qui plante tout le temps en bousillant des données que quand je suis vraiment obligé!
