plaintiger: sorry plaintiger, but MAC OS X is is so slow and for most of common user not so easy to use. Btw, how many applications can you find for Mac? For example when comparing with Microsoft it is minor ammount and not to forget Mac´s are so expensive without getting any added value.
Probably Mac users will not like me, but Macintosh is only waste of money. They have good marketing but nothing more...and security of computers doesn´t matter on operating system but on behaving of user, protection (firewall, anti-viruses etc) so it is very easy (but not true indeed) to say, use Mac´s, you´ll be secured.
