Use both PCs and macs, but am a diehard PC fan...not going to get into the argument of which is better, but if you know what you want...you can get a customized PC for $1000 or so less than a new G5 (with all the trimmings) and the performance is very similar. OSx is a great operating system, but lets keep in mind that Windows XP is an equally excellent OS (ive been using XP pro for a year and a half or so)...hasnt frozen once!! (yes thats right, not once). It is true you can viruses alot easier for the PC than mac but this is not because you cannot hack into a mac system. This is simply due to the fact that macs are owned by less than 5% of all computer users (so viruses are not commonly written for macs but they do indeed exist). ...ok, so my argument is a lil biased. Macs are great in their own respect, but they are definately not without their flaws...same goes for PC...choose wisely ;-)
