As far as Verizon is concerned, the Storm was a decent "iPhone killer", because it might have kept up to a million buyers from going elsewhere, perhaps from buying an iPhone. That's not chicken feed.
Ditto for the Storm 2 and the latest WM / Android phones.
I think there's too much emphasis on the App Store. Most people use four or five main apps, if even that many. Include the best and most common types with a phone, and stores are much less meaningful.
Too much emphasis, you guys want to downplay the app store because it's an advantage for the iphone. If an app store is not important why the heck is the competition rushing to get their app stores out there.
