Well she did a great job with Office. Office 2013 is superb. Let's face it, even with the annoying compromises in Windows 8, there's NO WAY windows could exist on phones and tablets with the Explorer UI/UX. Just not possible, that's why it failed on tablets.
Transitioning from the Explorer UI/UX to Metro/Modern is no easy task. I think after the initial shock wears off, people will realize what a task it was, and they did a pretty good job. As long as they keep updating apps and OS, it will be fine. For tablets it's great, it's when you transition back and forth that it's irritating and they really should unify Search. I mean really. They can't leave search the way it is.
At last - someone actually gets it. (Sounds sarcastic, but not only am I as serious as TIA (also known as tachycardia - a rather nasty form of irrythmic heartbeat that can be, and has been, fatal - among the more famous victims was Len Bias), it's something I've been trying to point that out since the Consumer Preview of Windows 8.)
Also, for all the detraction that has been aimed at the Modern UI, take a look at the sales numbers, now that it's out there and competing heads-up with Android (I'm referring specifically to Surface) and even the iPad. Here's a product with no history, and an alien UI - and it's selling solidly. (So much for WindowsRT being a failure.)
Here's the other side of the push with ModernUI (or as the late Paul Harvey would put it - the rest of the story). WindowsRT owners (and Surface owners in particular) will also likely give Windows 8 (WindowsRT's big brother) a second look - if they haven't gone and upgraded already. WindowsRT could actually drive sales of Windows 8. (Naturally, the reverse can be expected to happen as well.) Either way, Microsoft wins.
The Windows8/ModernUI App Store - The rubber well and truly meets the road here - the challenge for *developers* is to design apps that work on multiple form-factors (for now, I'm excluding smartphones running Windows Phone 8); those that pull it off will gain recognition and (for paid apps) sales and revenues. Until now, app development has been largely stovepiped - even within a category; WinRT is the first platform to broaden the base of small/casual app development targeting in a truly meaningful way. Yes - pulling this off would be, in fact, monstrous for Microsoft; after all, it hadn't been done before. However, it would be a bigger win for developers than even for Microsoft.
Office 2013 - for Office 2010 customers, this is largely an evolutionary, not revolutionary, upgrade - and that is *despite* the addition of SkyDrive Pro, touch support, etc. The improvements to Office (and the applications thereof) are all about mostly little things (reduction of RAM footprint, making the applications themselves friendlier to multitasking, reduced need for add-ins, etc.); however, as has pretty much been the case with every version of Office since 2003, it becomes yet another no-brainer upgrade from the previous version. (As I said I would, I'm running the RTM of Office 2013 today.)
