Mac or PC?

Some people may try to convince you that Apple Macs are inherently better than Windows PCs for anything involving graphics or photos, but this is simply not true.  In fact both are equally as good, since they both run on the same i7 Quad-core processors, and both use the same type of memory, so there's no particular advantage between them.  The only real difference are in cosmetic appeal, available software and price.  Macs do look very pretty, possibly an important consideration if you live in a designer home, but they are very expensive.  A Windows PC of similar specification to any given iMac will be considerably cheaper, have a much wider range of available software, and be much easier to upgrade.
