What you're saying seems to be backing up what I'm saying, though. SAP not having a usable iOS tool but working on Windows is a good reason for an enterprise to buy a Surface over an iPad, but unless SAP has working Windows Phone (or Android, or even Blackberry) tools, it also means that SAP just doesn't work well on any phone.
Do they? Does SAP have Windows Phone or other non-iOS handheld platform tools? Not a rhetorical question, I don't use it and maybe they do.
But if not, it would stand to reason to want to build good tools for whatever the most popular phone platform among your users is, which in the US for enterprise is unquestionably iPhone. And even if they do, given the relative popularity of iPhone it's still to their advantage to have good iOS tools, since it means that either people don't have to carry two phones (a personal iPhone and a corporate Windows Phone for SAP use) or they can not be stuck with an unpopular, poorly-adopted phone platform.
At the very least, there are no technical hurdles to having a completely MS-based backend and desktop platform with a robust iOS-based mobile platform regardless of scale. It's just a matter of having tools that connect well.
If this does work out, it could certainly make for a big selling point for iPads at the corporate level, as well.
We are kind of playing around the same thoughts...
SAP currently does not have decent mobile tool structure for any OS that I have seen. There have been some endeavors but it is very niche oriented.
One of the ongoing challenges has been that SAP never seems to have what the customer needs. They come close however customization always happens. So you enable a project, use what you can, create what you don't have and hope and pray that neither the OS nor SAP changes anything that requires a change. Enterprise level business plans in multi-year chunks and rapid changes are not in the picture.
This is what makes for most clients I have dealt with, a Windows win over OS X. Backward compatibility. Hardware flexibility. This is not something I am currently seeing nor think Apple is really looking at.

My company uses SAP.
As an engineer I have to report the hours I am working in projects in SAP, and I must say, I hate it. It's by far the worst piece of software that I have to deal with (horrible UI, extremelly unintuitive, slow, it doesn't adjust the contents of the windows and tables to the size of the window neither automatically nor at will, so I can't take advantage of my 30" display and see a a full week at once, or be able to select the Projects I am working on on the 20+ item list which only shows 4 or 5 at a time!... worst user experience ever has seen the light)
I know it's the ultimate tool for Beancounters. It's 0 and 1 p0rn0graphy for them.
Someone at Apple must be really excited about this news.
All you mentioned can be done. Just need decent dev's and process consultants. However to your point, it is custom work and costs extra.
Other platforms at the enterprise scale fall into the same arena. They talk a great game (usually) but require significant work to make it intuitively usable.
