I was with one of those companies. We all carried our own Lenovo's.
And I also attended a school board meeting whose members (like drunken sailors on shore leave), were hell-bent on spending us into oblivion with a $600 "no discount" iPad for each student. Eventually (and out of shear embarrassment) they were forced to suppress their fanboy-ism and go with something more practical.
I truly wish iOS could do the all the heavy lifting in this world. But it simply can't.
It is a problem when people set standards without really working through the use cases. Sometimes it can be a matter of corporations developing inhouse stuff only for one platform, but often it is just trying to make everyone the same.
Microsoft also has been guilty of this with Windows 8.1, which is why most businesses have balked at upgrading -- because it is making the desktop less useable for their use case.
The iPad is a consumption device, it is useful if your primary use is you want something very minimal to read books AND watch videos (reading only books an eInk device would be better), with minimal data entry (some email, some web browsing. It can be used in business when you are primarily are showing research and using it as a menu system (for ordering), but if you start using it to enter more data than just viewing - it really is not the device for you. I have had one for years which I use a couple of times a month for just that purpose. This is actually a very large market.
You then have people that do a lot of typing and data entry and using word processors, excel spreadsheets, coding.... people that spend a lot of time with their hands around the keyboard and mouse (I still prefer an external mouse)..... for these laptops (sans touch) are the ideal use case. I would say around 25% of the iPad market are people that would have been better served by a light laptop (similar to the new macbook) but that slight bit extra weight or bulk is quite annoying. I was on the road for almost 3 years straight and I can still remember thinking I can't wait to dump the laptop. The new Macbook is quite good at serving this need now that it is light and can be used for a full day before recharge. (I would take some extra stuff and leave it in the hotel for a week and only bring the macbook with a light sleeve and no extra devices during the day).
Now I know the Surface has it's audience as well, but personally I would find it annoying if I were in the usecase of an iPad and I brought the tablet with me and the keyboard then when I want to check something -- pull out the tablet, detach the keyboard put it back in the bag. I would also find it annoying if I were in the airport and I was trying to balance the thing on my lap etc. while using it as a laptop - it just would not seem that sturdy to use in that type of arrangement.
For me I have always fell in an either or situation around 95% of the time and I find that having something that is not quite as good for either of those usecases to be.... annoying.
There is no laptop, and no device that would suit me at my desk at home - so when I do need a device it does not have to be a very powerful computer....
I will be transitioning more from an iPad scenario to a laptop scenario again later this year so I will probably go with Macbook.
It is not that the Surface is not interesting or even that it is not great - it is just not something that fits what I see as my usecase.
And as Dell's own research indicated - if you have the Dell XPS touch vs non-touch.... a majority of people don't really want touch in a laptop... those that want touch in a laptop can go with Microsoft.
