@Ted T - I think this review was more on the hardware is my guess, and less on the software (Windows). Your assessment seems to correspond to the reviews I’ve seen elsewhere, especially the slowness.
I will never forgive Microsoft for the ridiculous amount of time the “delete file” feature in the XP/Vista UI took. Go to console, erase file - fast. In UI, sloooow. C’mon, are they doing an unindexed search of the filesystem to create an inode table or what, maybe using a bubble sort, and doing some miscellaneous laundry? Apple got this right, the UI is fast on the iOS. Forget the details, but I think they just spawn a thread task, and return immediately to the UI. Whatever the technique, it’s fast.
But Nielsen, rather influential guy in the UI area, has some a more detailed review of Windows 8 Surface RT (or whatever it is) and my conclusion is that this is a typical Microsoft 1.0 rollout. They’ll eventually get this right, but we are far from the days where MSFT owned the platform, so they don’t enjoy the luxury of the necessary time to get it right. Here’s the review:
Hidden features, reduced discoverability, cognitive overhead from dual environments, and reduced power from a single-window UI and low information density. Too bad.
