Yes, I read what Nick said, but none of it alters what I have said. Firstly, with universal Windows 10 apps the same app would be able to be used across phones, tablets, laptops and desktops. You seem to deliberately ignore laptops and desktops when talking about Windows, though the same app will work for all. For our own company website analytics, windows-based devices make up half of all visits - more than iOS, Android and MacOS combined!
Secondly, as has been previously indicated, analytics are misleading. The only Windows-based tablets that show up as such are those running Windows RT - the majority of Windows-based tablets do not use this. Most use full versions of 8/8.1 that is indistinguishable from laptops and desktops with web analytics - I personally have a device that fits in this category and verified this with our own company website analytics. To be in knowledge of this fact and still claim them being a ‘tiny amount’ is very mischievous.
Thirdly, is there a reason why those with laptops and desktops should be ignored with apps? Surely there is a reason you make them for phones and tablets that make them superior than using your website - why should those reasons also not apply to laptops and desktops?
