DEVELOPMENT: Is Windows Vista SideShow finally coming to Windows Mobile?
It's been a while that we talked about Microsoft's Windows Vista SideShow feature and while SideShow is still not too popular, finally there are some good chances we might see it officially coming to Windows Mobile as well.
Context & Ripple Effects
Windows Vista SideShow — Microsoft's feature for driving small secondary displays on laptops — has struggled for adoption since Vista shipped earlier in 2007, which is what makes this report notable: the::unwired sees real chances the feature will officially extend to Windows Mobile handsets. The claim remains unconfirmed, and Engadget's same-day pickup shows the story travelling on rumor strength alone, with no Microsoft statement behind it.
First-order effects
- If Microsoft confirms it, Windows Mobile OEMs gain a tangible differentiator — handsets that act as companion displays and remote controls for Vista PCs — at a moment when SideShow needs a visible use case to escape niche status.
Second-order effects
- Rival smartphone platforms would face pressure to match the PC-companion pitch, and peripheral makers building SideShow-capable secondary screens would suddenly have a mobile market to sell into.
Third-order effects
- The pattern points toward phones positioned as satellites of the desktop OS rather than standalone devices — Microsoft extending Vista's surface area across its device ecosystem, with adoption hinging on whether OEMs ship the hardware to match.
The trend: Microsoft is working to make its mobile platform an extension of the Windows desktop experience, with SideShow as one test of whether cross-device features drive handset differentiation.
