That being the case it is conceivable that enterprises may choose to adopt Windows 8 based tablets over iPads in a big way, possibly catching up Apple despite their current market dominance. It's unlikely that Windows 8 based tablets will become popular among consumers any time soon. However, with a tablet running a regular version of Windows 8, probably in an enterprise flavor too, they will likely be popular among developers and IT managers who are accustomed to working with Windows.
Because Windows 8 Tablets aren't likely to be popular among consumers, I don't think we will see them making a big impact in the BYOD to work model of Microsoft Windows 8 tablets in the workplace that we have today. However, with Windows 8 Tablets being more popular with IT managers we may finally see a lot more companies now buying tablets for their employees. And who knows, maybe after people get used to using the Windows 8 Tablet they've been issued at work they may want the now familiar interface and apps for their own personal Tablet. This scenario is largely what happened with PCs and Laptops in the past causing PCs dominate the "PC" market that Apple Started in the 80s with the Apple II and early Macintoshes.
Will things play out this way? Who knows but I think some sort of scenario like this is what Microsoft is gambling on.
