MAC's vs. Everything else

[DMbaseball1604]

I am using a friends powerbook right now and I'm about to get a new laptop...I was going to get a Dell 9100..but after using this laptop its making me wonder. It looks great! I was wondering if someone who knows more about computers than I do could tell me more about the pros and cons of getting an Imac...I do some video editing..and so I know that an Imac would be good for that..but as far as processor speeds are concerned it seems that anything with a pentium would be the better way to go because of its multi-tasking abilitiies and overall claimed speeds. anyways I would love to know what yall think..Thanks!
