The<br \/>\noriginal Power Macs G4 were 400Mhz, 450Mhz, and 500Mhz in 1999. That<br \/>\nwould make your iPhone pretty much the equivalent of the top of the<br \/>\nline 1999 Power Mac G4.<\/p>\n<p>And, the Power Mac G4 came with 256Mb of memory (compatible with the<br \/>\niPhone 3GS) and only a 10Gb to 27Gb hard drive, so a 32Gb iPhone would<br \/>\ncontain a lot more space. \u00c2\u00a0So, the iPhone 3GS is pretty much equivalent to a ten year old, top of\u00c2\u00a0the line Macintosh computer.<\/span><\/span><\/span><\/span><\/span><\/p>\n<p><a href=\"http:\/\/www.ipodobserver.com\/ipo\/article\/EDN_iPhone_is_Precisely_Designed\/\">EDN: iPhone is Precisely Designed  |  News  |  iPodObserver<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The iPhone is a fully fledged computer in it&#8217;s right, but how does it compare against &#8220;real&#8221; computers?
