I believe the story is misleading. Apple Corp sued Apple Computers because Apple Computers was infringing on the name Apple (and yes, also used an apple as the company trademark). Just like I couldn't call my garbage business Microsoft Garbage (this is infringing not only on the Microsoft trademark, but business strategy as well).
Here, Apple Inc. is suing VSBT simply because both use an Apple for identification (if I'm not mistaken, Nature(TM) Inc. created the apple). I'm pretty sure this will get thrown out. Apple itself argued that it's icon was different from Apple Corps. because it had a "bite mark" in it. Since VSBT doesn't have a bite mark, and involves different coloring and a different general apple shape, I don't think Apple has a leg to stand on. Also, anyone remember when Apple's logo was a multi-colored apple? If VSBT had the "stylized" apple before Apple Inc., that's obviously prior art (not that I know this is the case).
