okay, i'll be the discordant note and be flamed for it...
I've had macs, and they suck, at least for me.
from time to time i have a convo with someone who has had a bad experience with mac, and its a shame.
yes, and powerful PC would be considerably cheaper then a mac.. however, heres the problem, in 2 years, your going to have to buy a new one. I have a G3 tower, which i got 5 years ago, and it was used for 3 years before i got it, and it still works GREAT, i have a mac mini, which i bought 2 years ago, and it works GREAT, I have a macbook which i bought a year ago, and IT works great.
my buddy has a decked out PC laptop which he bought 2 years ago, for half the price of my macbook, HOWEVER, he already needs to get a new one. The screen is crapping out, the hard drive has had to be replaced the CD burner doesnt work anymore... SO now he's going to have to spend another 6-800 dollars, when if he had of taken my advice, he could have spent 1700 bucks, and his computer would still work, and he wouldnt have lost all the stuff he lost when his hard drive crashed.
A mac with problems come few and far between. and if there is something wrong with it, apple is VERY good to fix it for you, usually at no cost. just because you had a bad experience doesnt mean they suck.
My macbook has 2 gb of ram, and photoshop FLIES on it, no delays at all, its very fast. If you run less than 1GB on a mac, your just being foolish.
