how many of you have switch from pc to mac? im really fed up with windows right now and ive liked the macs ive used so far so im thinking about giving them a try. my main concern is, will it be fast enough? im currently using a 2.5 ghz pentium 4 hp. The powerbooks im looking at are only 1.25 ghz... how much do you think that would be equal to in pc ghz? sorry if this is a confusing question.. maybe i should have tried a mac message board instead, but i was already logged in here and it was on my mind. anyways.. thanks in advance for all the help!
