If WinP is a success in the Enterprise it'll be for the same reasons everything else they sell there is a success: massive reseller commissions. IE, they'll shovel the carriers truckfuls of cash so the B2B teams only sell WinPhone, presumably by badmouthing Apple's enterprise support.
ABIs reason for WP8's growth is with iOS7's remote management of tablets and apps as I understand it according to the source. Big deal - fix it.
This enterprise space is where Blackberry should fill if they consider using windows phone , And Microsoft should fix VPN , File manager and Miracast in windows phone 8.1
Windows as got to be upgraded faster to compete with ios an Androids,as Applications are not much available on Windows,as the Tiles home screens needs changing as to many Tiles just Spoils the Look of Windows phones,an now Microsoft as over taken Nokia what will be getting from Microsoft now in 2014,they are going to be under alot of pressure to offer better functions on there own Windows phones
Wp8 is so good i ditched my xperia z for a lumia 920 and i am happy with my choice
WP will never gain place in buisness enterprise market, unless they include VPN in their OS, as currently it dosen't have this & most secured business e-mail pltaforms are currently using VPN.
I will wait for Sony Windows Phone 8 devices because they won't ditch physical QWERTY keybord for WP (enterprise Segment) Japanese understand better :) :)
