This is a most excellent place for technology news and articles.
The "modern" (aka metro) interface was possibly good on a phone or tablet. Arguably even possibly on a touch screen laptop (not for me though). However it had no business being on a mouse driven computer or even worse a server operating system (Windows 2012).
Even the idea for "metro" apps was horrible. Full screen only. The whole reason the OS is called windows is because you could have two "windows" with two different applications on screen at a single time.
MS could have still included the metro interface if they still shipped the classic Start menu as an opt-in. Yes, its the first thing 90% of users would opt-in to, but at least it wouldn't have had Windows 8 be a rotten footnote in the history of computing.
