Techcrunch has the details for the Microsoft Surface RT Pricing:
Microsoft today detailed pricing for its Surface tablets, at least those running the scaled down RT version of its upcoming Windows 8 operating system designed for use on low-power processors. The Surface starts at $499 for an entry-level 32GB version without the Touch Cover with integrated touch-sensitive keyboard, while one with the cover runs $599. At the top of the line, a 64GB version with the touch cover included costs $699.
Competative with the iPad, which is good, just remember than other than MS Office, the RT will only run “Store 8 Style apps” (or in the Banned Speech - “Metro Style apps”).
