Judging from experience I know graphic design now as really gone a long way even more than expected and its all to the screen gurus with the magic mouse and their non persistence in developing new ideas with baddest concept. Now talking about logos design, it is another form or expression at which a group or company is recognised e.g apple laptop can be recognised by their logo which is "Apple" now paying attention closely at the logo it is not completely complete (as much as I can explain) it as a kind of hole at the base and right side although normal apple doesn't make a complete circle, the hole at the base and right side of the apple wasn't mistakenly there the hole was made deliberately like a bite. on the apple which makes lots of sense because the memory of any computer is measured in byte... So bite/byte all rings a bell... Nice concept they gat there huh
