There's an entertainment center for Windows that does all those things, though: Apple's iTunes. But it's a Windows 7 app, so it runs in the legacy Desktop part of Windows 8 that's hard to use in a touch or tablet environment, as I discovered when I recently compared media tablets.
What if Apple made a Metro version of iTunes, similar to the iOS version that works quite well on an iPad, but with the ability to import local media and create ringtones that desktop iTunes also has? That would turn Windows 8 into an entertainment powerhouse, with full, flexible support for music, movies, TV shows, podcasts, e-books (which Metro can't do outside of Kindle books) and perhaps even photo albums across both PCs (Windows and OS X) and Apple mobile devices, including the Apple TV, which remains the best media-streaming box out there.
Suddenly, there'd be something really useful -- and important -- to be done in Windows 8's Metro environment, which is supposedly the future core of Windows. If Microsoft ever made a good Office app for Metro (no sure bet), then Windows 8 might get a second look in business, as well as for home-business users. An iTunes/Office duo in Metro would be killer.
Of course, Apple has no strong reason to make a Metro version of iTunes, any more than it has to make a version for Android. When it first made iTunes available for Windows in 2003, that cemented iTunes's status as the media center. Back then Apple had no mobile devices (the iPod was a mere two years old) and Macs were just coming back from death's door.
Today, Apple is a cash machine, with strongly profitable mobile and Mac businesses. It already has most Windows users, and it knows that withholding iTunes from Metro won't reduce its user base. Instead, WinXP and Win7 users will stay where they are, get Macs, or -- most likely -- shift to iPads for media consumption, giving Apple both hardware and media revenues.
Yes, if Windows 8 PCs were to resurge, boosted by a Metro iTunes version, Apple would net more media revenues but at the potential cost of lower hardware revenues, which still dwarf iTunes revenues. Perhaps one day that calculation will change. PC users can only hope.
