Two things, firstly, an editorial is typically a well researched and thorough piece of writing, not 8 short paragraphs.
Secondly, in line with the my first point, I had to stop reading here:
"[Referring to WP7], besides the Windows Phone 8 launcher skin, it will not get any of the other Windows Phone 8 upgrades, such as IE10, the DataSmart, SkyDrive music player etc. Given the reliance on the Wallet app for in-app purchases, it is not even clear that this developer feature will be supported by Windows Phone 7 handsets either."
Now, I don't deny that this statement potentially could be true. But as of right now no announcement has been made on it. Nothing has been said; so to me it's wrong to incite anger or panic or wrath of the nerds based on an unverified statement. Especially one presented as fact on a reasonably reputable technology website.
