Who cares what program you have. Both are billion dollar mega corporations either way. Here, these are my opinions.
Apple was about a worthless PC company until a few years back I feel. N one ever talked about apple, it was the windows shot. Windows 2000, then XP and all that. The I Macs are indeed fuckin pimp shit as are those little box ones the Emac or whatever. I havent used one since school, but they are nice.
Windows has been delivering quality computer operating programs since '95. You know what I mean, solid as fuck. All of mine have worked great. I've nver had a virus in the 6 years I've owned 3 computers. (got up to date as I bought) I started with windows 98, now I have XP. Shit freezes once in a while tho..
...but the real battle is with gates and his ex boyfriend who owns apple. They have some issues to work out.
