Obviously, not there are Intel Macs. From what I understand, Intel Macs and PPC apps are no different right? I know that Intel Macs are faster, but most Macs are fast so a difference between .5 seconds and .2 seconds wont really be noticed. But what are the differences between Intel and PPC Macs? Are there any differences with software, capabilities, etc? The only thing I know is that many apps work for Intel Macs but some run slower due to Rosetta.
