The Verge has a preview of the final version of Windows RT which will run on the ARM-based tablets that will be priced to compete with the iPad.
Microsoft is betting big on this, but you can still see the rough edges. Small touch targets and traditional mouse-optimized apps on a touch tablet are terrible when everyone is familiar with the easy-to-use iPad. Microsoft is trying to have it both ways, leveraging existing apps while building new apps at the same time. But if users need to spend any time in desktop mode, they’ll be disappointed. And it’s not powerful enough to please traditional desktop users. Hopefully this is just a short-term transition phase which will be remedied soon by lots of native touch-optimized apps.
