I haven't read through all of these replies on this debate, but I'm going to add this...
It really is too bad that all of these large companies couldn't put their pride aside & actually give a damn about the consumer for just ONCE. It really is too bad that the only thing that ever matters to a company, particularly the large ones, is the bottom line.
Now, keep in mind, having 2 separate technologies to choose from does have its Pros, as well as several Cons. IMHO, the 1st Pro that comes to mind is providing the consumer with the option to choose. This is usually a good thing from a business standpoint because it leads to friendly competition. Friendly competition generally leads to more competitive pricing.
With these 2 technologies battling it out like Godzilla vs. King Kong, I don't really see a price war coming anytime soon. Because they have distinctly chosen to take completely different paths for their technology, it's almost going to be like Microsoft competing with Intel. Well, you can't really compare those two because they do different things.
Another thing to keep in mind here, these technologies aren't really mainstream yet. What I mean is, go up to 10 people at your local grocery store & ask them which technology they think they'll go with upon release. At least 8 of those 10 people will look at you like you're crazy. Why? Because this hasn't hit national advertising & marketing yet at the mainstream level. So, beware average consumer, because you're about to be blasted with more technological information than you're prepared for.
Bottom line here is this...Having 2 separate technologies will hurt the general public / average consumer more than it will help the economy. Why? Because we would be much better off with one inexpensive, cost-effective solution.
