Don't worry, I won't be. Apple hasn't given out tech behind the magsafe connector and I doubt they will. There aren't any 3rd party power adaptors for the MBPs and MBs, and there won't be some slap on attachment for the 17" MBP to extend the battery life like on the iPhones or iPods.
Check it!
The only way manufacturers have gotten around the Apple patent is to get their own magsafes and merge them with their other products. Rising the prices since they have to fork over $79 for the power adaptor.
Aiden nailed it of course, and I will co-sign and add that it involved anything that cranks the CPU and GPU to max on a pretty much constant basis.
It doesn't have to me 3D modeling and HD encoding, but running VMs, AutoCAD, mathematical computations, etc fit the bill as well.
I think people are forgetting that the 17" MBP is touted as a desktop replacement, and by "desktop" I don't mean iMac.
