Re: [Development Platform]Is Windows 8 a good platform to build apps for?
Windows 8 has been a huge flop, however Microsoft want to try and word it. It's release saw PC sales go down further rather than up, it's been the source of constant criticism by not just ordinary users but UI experts also, and most people I know that do like it casually remark that they've installed 3rd party plugins to bypass the start screen and replace the start button anyway.
So sure, if you want an academic exercise then go for it, but in reality there's a good reason why few people have targeted Windows 8 specifically (despite a few campaigns Microsoft have been running such as StackOverfow competitions.) If you actually want as many people to use your app as possible, which almost everyone does, then targeting the Windows 8 app store is a complete non starter.
