I think sometimes it just takes a little while to translate in the maket.
A more recent update by the same website was released yesterday concerning Windows Phone and Microsoft:
Verizon will offer Nokia Windows 8 Phones -- could this be the jump-start Microsoft needs? | Computerworld Blogs
I actually think it is smart on Verizon's part to slowly implement it into their ecosystem. I'm a Verizon customer. I grumble now about my one (HTC Trophy) phone choice; but when looking from their perspective investing your market heavily in any new product is a poor choice. It's always best to let it weather the storm a bit initially until it's beefed up to do some serious action in the market. I think in the next one or two years we'll begin to see a huge push for Windows Phone by Verizon.
