re: Microsoft Surface Vs. Dell Venue: Tablet Rivals
True, Windows software is much more deeply woven into business infrastructure. But the article wasn't really about Windows devices being usurped by iOS devices, per se-- it was about Microsoft's Surface tablets specifically.
On that subject, Apple claims that more than 80% of tablets activated in the enterprise are iPads, and everything I've heard from research analysts supports this. So if the Surface is going to gain ground, it either needs to take some enterprise share away from iPads (in which case a "tablet with iOS" vs. "tablet with Windows 8.1" conversation becomes relevant) or it needs to replace retiring PCs and laptops (in which case the point isn't Surface vs. iPad so much as Surface's hardware convergence vs. other notebook options, such as clamshell Utrabooks, other convertible form factors such as the Lenovo Helix or the Dell Venue, etc.). In most scenarios, in other words, Microsoft is selling to potentially slim fractions of the market: the people who want a premium tablet but don't want an iPad; the people willing to pay top dollar for a portable, all-in-one convergence device; the people whose data revolves more around Microsoft's ecosystem of apps and integrated services than around Apple or Google's; etc.. That was the point of the article-- that the Surface tablets are much improved but still basically target niches that make breakout success questionable.
But if the article implies that employee preference for iOS means iOS is somehow pushing Windows out of the enterprise, then, no, that's not what I meant. Microsoft, as you point out, is still way more "business" than Apple, even with Apple recently making a few overtures to the enterprise and Microsoft spending more effort wooing consumers. Windows software will be crucial to the world's businesses for some time to come. But iOS isn't irrelevant to the enterprise, or to Microsoft's Modern UI and Surface plans.
