The problem here is that devs have to work twice as hard to make suitable apps. For example, the 1366*768 and 1920*1020 screen resolutions have a 2:1 and 16:9 aspect ratio,respectively and are commonly found on computers and tablets, where high PPI isn't always important. On the other hand, the WVGA (800*480), WXGA (1280*768) resolutions are particularly important for Windows Phone and are pegged at the 15:9 aspect ratio. In addition, the PPI found on WP (the lowest so far is ~193 PPI on the HTC TITAN 2 and Lumia 625) are mostly higher than those found on Win8 and WinRT devices, where high PPIs already make the desktop hard to navigate. This difference will only grow with the introduction of 1080p Windows Phones.
Also, there's the general preference for non-iPad tablet users to prefer landscape instead of portrait, and so on.
