I would say no problem, but I had to deal with seeing 3OH!3 for two minutes.
proof that a mac isn't the answer to everything. and don't even think about saying "get office for the mac". it fucking sucks and you know it. i have a macbook pro and this is the one thing that drives me absolutely batshit - i can't bring a ppt deck home and have it render properly in office 2008 for mac. it's absurd.
This doesn't prove anything, i'll bet he uses a mac too. I have Office for mac and it's never given me a problem... Ever.
