Microsoft's first ever computer, the Surface with Windows RT (or "Surface RT" as I will henceforth call it) is a mixed bag. The design and build quality both impress, and Microsoft's twin typing solutions—the 3mm no-moving-parts Touch Cover and the 6mm real keyboard-equipped Type Cover—are remarkably effective.

The screen resolution, however, is substantially lower than those of its comparably-priced competitors. The touchpads of those covers are wretched (in the Surface review, having used them for a week, I thought they were poor; with several months under my belt, I now think they're downright bad). The processor is underpowered.
But the biggest issue with Surface RT is its operating system: Windows RT. Windows RT can only (officially) run applications using the Metro user interface and the WinRT API. These were thin on the ground when I reviewed Surface RT, and they're thin on the ground today.
