When a certain business has a huge market share, it's nice & fine until shortages happen, and soon that certain business is scrambling to continue that market share, but the smaller buyers are left in a lurch (you know what happens).
My point is that some buyers will be trampled in the process and will seek new business dealings elsewhere. Once they leave, it is really difficult to get them back and certainly they will learn that their new business supplier has perks beneficial to them, so their business grows positively.
Such is the case, Intel vs AMD. One will say that Intel is so huge that losing a few clients is nothing to worry about. Just like the wee leak in the dike. It starts out little, but it grows bigger. I hope that AMD doesn't get too big too fast. A steady growth helps us consumers because its based on stability which breaks down to decent prices with advanced technology. A win, win situation for AMD and us.
