Every doctor I know works on a laptop or convertible device. All of these seem to have touchscreens. One doctor uses a stylus to navigate through the medical documentation interface and its controls. Another uses the touchpad, even though the screen 3 inches away is touch-capable.
These are the types of people who use touch devices. They work on their feet, move around, and need to bring their data and applications with them.
Windows 8 won't help them much because all of their work is done inside an application. It might be 3 seconds quicker to launch the app in the beginning of the day because they can click on a big icon with a finger, but otherwise they don't see the UI fka Metro anyway.
The UI fka Metro is designed for phones, pads, and tablets... and the TV. It works well from 10' away on a 46" screen. But then MSFT went and not only left WMC features out of Metro, they actually left them out of Windows entirely unless you buy or upgrade to the Pro edition. What could have been an extremely slick integrated experience for Metro Apps and MC features (e.g. TV Guide as a tile, Photos as a tile, Music as a tile). But instead there is a Photos tile (that doesn't seem to see my photos for some reason and just shows empty folders?), AND there is the pictures + videos feature in 8MC that works. There is a Video tile that works part-way, AND there is again the pictures + videos feature in 8MC that works. There is a Music tile that seems designed to sell me stuff and doesn't show the music in my library, AND there is the 8MC music feature that works. And on top of it all, there's still Windows Media Player!! Who designed this $h!t? Furthermore, the UI for 8MC works better for keyboards and mice than the UI fka Metro. Why the Metro team deliberately ignored all of the insight learned by the MC team over the years is befuddling. Features such as the clickable arrows to scroll the page could have been easily incorporated... but weren't. WHY?
I've been using Win 8 for just 2 days now. I tried it once before with an early beta and ran into performance issues on my older HW, but my current HW seems to run it ok. I've run into various HW compatibility issues (it's a 2005 MB running an Intel Pentium on 915/ICH6R with 2GB RAM and lots of old devices, so no fault to MSFT on that), but I've been able to get most everything (except Hyper-V Client) working in Win 8 x64, including my integrated audio, Radeon X1800XL GPU, integrated LAN, Hauppauge analog tuner card and various other bits. But I have yet to see anything other than the file-xfer progress dialog and the new task manager that excites me. And I have seen a lot that doesn't excite me, such as having to learn new ways to get to the same configuration GUIs we've been using since XP. And I have seen some things that are just plain stupid, such as MSFT completely missing the opportunity to create an integrated interface for the living room that includes not only the existing 7MC features, but also new apps that are going to be appearing on phones, tablets and desktops everywhere.
