•The selection of available apps is still weak. The number of apps is growing slowly, but it’s still a tiny fraction of what the Apple and Android ecosystems have to offer. And many of those apps, even some from Microsoft, have a “we’re still figuring out how to work with this user interface” feeling to them.
•This device, with its 16:9 display, works best in a horizontal orientation and is awkward (to put it mildly) in a vertical arrangement. There are benefits to this design, including the ability to snap one app (like a Twitter feed) into a pane on the side while you work with another app in the larger space alongside it. It also allows you to watch HD movies the way they were shot. But this design choice makes reading ebooks using
Amazon’s Kindle app a two-handed operation. (To make things worse, the RT version of the Kindle app only shows a single page in landscape orientation, while the x86/x64 version can display two pages. Why?)
•Working in a world where Internet Explorer is your only browser can be frustrating or even infuriating. Some websites, for good reasons or bad, don’t work properly with Internet Explorer 10. For a ZDNet blogger like me, that’s a showstopper, because the ZDNet back end doesn’t allow uploading of images from Internet Explorer 10. The action simply fails. On a Windows 8 PC, I can just flip over to Chrome or Firefox. With Windows RT, the option to use an alternative browser simply doesn’t exist.
•The Office 2013 apps in Windows RT are almost but not quite the same as their x86 counterparts. For most tasks, that’s no big deal, but occasionally I run across a document spreadsheet that depends on Word or Excel macros. Oops! Macros aren’t supported on Windows RT.
•The lack of comprehensive driver support is an issue. A big theoretical advantage of Windows RT is that it allows connections to printers. Except there’s no RT driver for my printer, which means that advantage is still theoretical. Likewise, plugging in any USB device other than a flash drive is likely to be frustrating. I have yet to find a USB-to-Ethernet adapter that Windows RT supports, for example.
