Owning a HP Specter X360, I've already seen some benefits of its folding capabilities, mainly for stand purposes and sometimes so I can have the screen closer to me when I'm watching movies. Still, not having 360 capabilities is not a deal breaker, I consider it more as an added bonus.
IMHO, I think a big part of the market is not yet ready to embrace convertibles seeing them mainly just as a gimmick. I mean its not a feature you're required to use. Its just good that the 360 capability is there when you need it but then again, this will cater to ordinary people who prefer traditional laptops.
