I've been looking at the imac G5 for a few weeks now and was wondering if anyone has one of these and what you think of it. With the advent of the Intel chip, would it be a good investment now? Always having just a PC, can one download Windows programs to a mac or is this our of the question? I do know that Norton makes anti virus/firewall software specifically for the mac. Would a router be a good idea as I've always used on on my Dell. As you can gather, I've never owned a mac...yet.
