The scores for graphics are higher than under Windows 7 RC – lifting the overall score – but the experience is not much changed: it’s still snappy and responsive.
Drivers are provided, out-of-the-box, for for all of the XT’s hardware bar the multi-touch screen. The touch screen’s manufacturer, N-trig, have made Windows 7-specific drivers available; although the as-of-writing link on the page refers to the “Windows 7 Release Candidate”, the download itself seems to contain up-to-date drivers for Windows 7 RTM.
To enable automatic re-orientation of the XT’s display when switching between notebook- and slate-modes, install the Dell QuickSet application (the XT does not have an accelerometer like, say, the iPhone). Dell do not appear to be providing Windows 7-specific drivers (and other software) for the XT, but the Windows Vista version of QuickSet seems fully compatible with 7.
UPDATE: The KingSpec SSD featured in this post died after 10 months.
UPDATE 2: A second KingSpec SSD lasted just a further four weeks before it, too, expired.
