Despite Microsoft's execs' best attempts, the company's mobile strategy, at least as far as actual smartphone devices go, is uncertain at best. However, that's not stopping a few of Microsoft's key friends from diving in without fear. Acer continues to promote its Jade Primo, for example, one of the few non-Lumia Windows 10 smartphones that can boast of Continuum for mobile support. Soon, HP might join the fray. According to a source, the company's intriguing Elite x3 is pretty much on schedule for a June launch, which could spice things up a bit for the Windows 10 mobile market.
