I tried out ASUS at bestbuy too. And then the SurfaceRT at the local mall. I felt the glossy finish of Asus was more appealing. Also, responsiveness was better than Surface RT.
One thing that annoyed me on Surface RT. I installed AccuWeather app from the store. The animated clouds were showing up on the live tile. But when the app was opened, it slowed down the whole system.
In general, I also felt the many standard apps had a not so desirable behavior.... which is.... the animated icon showing the fetching of the contents. on many apps I opened, I had to wait for the thing to fetch. Although this is more about the app design, but I felt some content should be pre-fetched.
