Our previous announcement was for Windows 8 support. This adds support for Windows Phone 8 (whose SDK came out after we launched the Windows 8 version) as well ;)
I get Windows 8 and Windows Phone 8 confused all the time (I'm not being sarcastic here, even though it might sound it - I genuinely do! The names are too similar).
As a developer, it also doesn't help that Microsoft made a lot of noise about them being on the same kernel, even though there's hardly any API overlap between them.
I'd be interested to find out what motivated you to target this platform. Do you have an internal requirement to target every single one of the mobile platforms out there? Does this platform offer something the others don't? Has the vendor provided incentives (like we know they are forced to do by market conditions)? Would you still consider targeting this platform had the vendor not provided any incentives?
Also, how would you compare the experience of working with this particular SDK compared to the others? More streamlined? Less streamlined? Hopelessly frustrating technology soup? Best thing since sliced bread?
