actually i want to change my choices if i may:
best:
the PET!!! that is really what started it all!(i dont care too much for typewriters and electric calculators)
worst:
couldnt handle their finances and died :-( that was sad because one of their favorite machines(the Amiga) didnt do to well after that and wasnt developed(we are still wating), and lots of good software developers left that particular platform(even though there were plenty of users still) it all went down hill from when commodore died :-(
