On the flip side, Microsoft's upcoming double screen device actually looks usable as a sorta tablet/phablet hybrid. If it's not too big in hand and fits as a large phone, I can see myself using it while on the road for work.
I like Microsoft's solution to a folding phone better than Samsung's. Microsoft also has the opportunity to this phone into a gaming device. It could work like a Nintendo DS and the could sell a gampad dock for the phone to slide into or allow pairing of an X-box controller. They are already planning a gaming streaming service so this phone would fit well.
