As a specialist in CB & CI design, I have just a few points to make.
1) Apple MUST protect their Trademark, as many here have said, or risk losing... or at the very least diluting...it, and making it harder to protect in the future.
2) Yes, the "W" logo as it stands on this page is quite different re: the Apple logo. HOWEVER, as all of you Apple fans should know and see on the product right in front of your face, what happens to the differentiating colors and form when the "W" logo becomes uni-colored, or only embossed in plastic at 1x1 cm or smaller? Or the logo is upside down, as it may be in every day use?
3) as someone above has mentioned, Woolworths also has an electronics retail business. So they go to China, get a cheap looking knock-off of an iPod, and have their "W" logo embossed on it... only for a promotion. All of a sudden you have these quite similar iPods all over the place, that "must be" Apple's (at a cursory glance), and the whole thing is a piece of shite, causing people to consider all Apple products to be the same low-quality crap... and spreading that "fact" to family and friends. What if Woolworths decides to emboss their logo on toilet-bowl disinfectant bricks for their home wares division?
Do any of you NOW see the problem if Apple doesn't at least try to protect their logo?
In the legal process, Apple may request and be granted that the "W" must at all times be in green, never embossed or uni-colored without the gradient, and never be placed on any product at smaller than say 1x1", and always be accompanied by the word-mark "Woolworths". Suit over, and Apple wins.
You you could also say Woolworth wins too, because now there is a definite set of guidelines to follow that won't ever get them in trouble.
PS: Unbelievable that there are so few designers left in the Apple community that know these things. Guess that's the price to pay when Apple saved itself by becoming a consumer products co. first, and a designers dream-machine/platform after the fact.
PSS: The "W" logo is definitely too fat, difficult to print on all products (screen-printing) and most surely would be "re-worked" and/or reinterpreted to be printable at small sizes, losing, or blurring the identity. Trash the design... start over.
