"This equates to a little over 4,900 Windows 8 tabs being sold via distribution."
Actually...I wonder if that number is all that bad. Before you all explode, hear me out: Windows 8.1 didn't land until August 27, 2013. Most corporates wouldn't dream of touching a Windows OS until it had hit service pack 1. So it isn't unreasonable to assume that the majority of those units were snapped up not to fit a given "now" need, but instead were bought for "proof of concept" work eyeing future deployments.
How many businesses are there in the UK that really, honestly, need tablets for their work and aren't already deeply embedded into the Apple ecosystem? I'd guess that 4,900 tablets probably represents around a thousand companies at least putting in the effort to seriously consider Windows as a tablet platform for their needs in 2014.
Maybe those aren't stellar numbers...but corporate compatible Windows 8 (i.e. service pack 1) has only been out for about 4 months, compared to a Apple ecosystem that's 3.5 years old. It's the next 8 months that will tell the tale. If we start to see big corporate wins in the UK in the first half of 2014 we'll know that some of these were POCs that proved out.
If not, I'm thinking we can safely assume that Apple won this battle and Microsoft haven't a snowball's chance in a neutron star of clawing their way back.
